One of the common problems encountered with the Mixer Toolbar is that its '''input selector can appear greyed out or lacking the expected choices''', thus apparently preventing the user choosing the required recording source. The purpose of the selector is to link to the current mixing device (assuming this device offers a choice of input sources) and thus save the user going through a series of system menus to choose the source.

== Mixer Toolbar issues and input device selection ==
 +
In [https://web.audacityteam.org/download/ current Audacity], all available inputs are selected in [https://manual.audacityteam.org/o/man/device_toolbar.html Device Toolbar] or [https://manual.audacityteam.org/o/man/devices_preferences.html Devices Preferences].

It is often assumed that Audacity controls the sources displayed in the input selector, but in fact the sources offered are governed by the drivers of the sound device that is currently selected in the Audacity Preferences. Drivers are a big issue on Windows machines, and it often happens that machines purchased new will only be supplied with generic Microsoft drivers. These may prevent the input selector from displaying all the possible inputs the device has (or any at all), or from linking properly to the system mixer (so that for example you end up always recording from line-in, or cannot apparently record at all, whatever source you choose on the input selector).

This may prevent the audio device linking properly to the system mixer, so you may end up always recording from line-in, or cannot apparently record at all (whatever input source you choose). Another issue may be that you won't see all the inputs that your device potentially offers.  
  
So the first step towards rectifying input selector problems is to go to the {{Menu|Audio I/O tab of Audacity Preferences}} ''(Devices tab in current Audacity, or in legacy 1.3.9 or later)'' and check that the playback and recording devices are explicitly set to the correct sound device you want to use. For example you may have multiple sound devices such as built-in sound and an external USB device, so you need to choose between them. If you are on Windows and experiencing problems, choose your sound device explicitly, not Microsoft Sound Mapper (which is intended to map to the currently selected default Windows sound device, but may not always do so correctly).

So the first step towards rectifying input problems is to open the {{menu|Preferences}} and choose {{menu|Devices}} . Find out what inputs are available and ensure that the playback and recording devices are explicitly set to the correct device you want to use. For example you may have multiple sound devices such as built-in sound and an external USB device, so you need to choose between them. If you are on Windows and experiencing problems, choose your sound device explicitly, not Microsoft Sound Mapper (which is intended to map to the currently selected default Windows sound device, but may not always do so correctly).

{{tip|'''Note that on [[Windows 7 OS|Windows 7]] and later, initial driver setup typically disables all the inputs except for the built-in microphone.''' It is strongly recommended to use the [https://manual.audacityteam.org/man/windows_accessing_the_windows_sound_controls.html Sound Control Panel] to show and enable all disabled devices so that recording applications like Audacity can see them.}}
  
Note that some sound devices have individual analogue to digital converters (ADCs) for the different inputs such as microphone and line-in. Where this is the case, these inputs are treated as separate recording devices (e.g. Line-In: Realtek, Microphone: Realtek) and should be selected in the Audio I/O tab, not in the Mixer Toolbar selector, which will be greyed out. In a similar way, Windows Vista and Windows 7 always treats recording sources as "devices", so on this operating system the selector will always be greyed out and input sources must be chosen in the Audio I/O tab.  See [[#vista|below]] for more explanation.

===USB and Firewire recording devices===
+
Note that some sound devices have individual analog to digital converters (ADC's) for the different inputs such as microphone and line-in. Where this is the case, these inputs are treated as separate recording devices on Windows (for example, "Line-In: Realtek" or "Microphone: SoundMax"). These inputs can be most conveniently selected in [https://manual.audacityteam.org/o/man/device_toolbar.html Device Toolbar] in [https://web.audacityteam.org/download/windows current Audacity] but in legacy Audacity before 1.3.13 they must be selected in the Audio I/O or Devices tab of Preferences and not in the Mixer Toolbar selector which will be greyed out.
  
Note that if your selected recording device is a USB or Firewire device, these normally do not have multiple input sources to choose from, so Audacity's input selector will grey out. This is normal, and just means the selector is not needed. Any necessary configuration should be done on the device itself, or in any control software that comes with it. Examples of devices which will normally not require use of Audacity's input selector are the Griffin iMic, USB turntables and a wide variety of USB and Firewire mixers and interfaces.

Note that if your selected recording device is a USB or Firewire device, these normally do not have multiple input sources to choose from, so Device Toolbar or Preferences will only list the device as a single choice and the input selector in legacy Audacity will grey out.

[[Multichannel Recording|Multi-channel recording devices]] do allow limited input channel selection in Audacity where the drivers support this, though only [[Multichannel Recording#Suggested devices|a few devices on Windows]] allow recording more than a pair of two channels at once unless you compile Audacity with [[ASIO Audio Interface|ASIO]] support.

Also check your sound device is not already in use. If you are on OS X or Linux and the sound device is already being used by another application, Audacity may not be able to access it for recording and the Mixer Toolbar input selector will appear greyed or minimised. Generally, this is not a problem on Windows, though issues with some applications are known. For example speech recognition in Word and the Fraps screen capture software are known to prevent other applications from using the sound device to record from a microphone.

Also check your sound device is not already in use. If you are on Mac or Linux and the sound device is already being used by another application, Audacity may not be able to access it for recording. As a result, Device Toolbar, Preferences or the legacy Mixer Toolbar input selector may be empty of devices. Generally, this is not a problem on Windows as long as you choose MME host in Audacity, though issues with some applications are known. For example, speech recognition in Word, Skype or the Fraps screen capture software may prevent other applications from using the sound device to record from a microphone.

==OS X-specific issues==
 
 
 
OS X has a very different audio hardware interface to most other operating
 
systems. As a result, there may be no (or greyed out) Mixer Toolbar, or only one audio recording source available to Audacity, which will be identified as "Default Source". You will need to click on the Mac hard disk, then on <span  style="background-color: #CCFFCC; color:#a0522d"> Applications >  Utilities >  Audio-MIDI Setup</span> and select your required recording source (e.g. Line In) in the Audio Input section so that it becomes the source that Audacity will use. This is how Audio-MIDI Setup looks in OS X 10.4:
 
 
 
[[Image:AudioMidi.png|left|535px]]<br clear="all" />
 
 
 
 
 
In OS X 10.0 and 10.1 there was no Audio-Midi Setup, so choose your recording source at System Preferences > Sound in the Apple Menu.
 
 
 
If you are on OS X 10.4 or higher and are using the current Audacity version, this has a later version of our PortAudio interface and may enable you to select sources in Audacity's input selector (or possibly in the "Recording Device" dropdown in the <span  style="background-color:#CCFFCC;color:#a0522d"> Devices tab of Preferences</span>).

Some high-end multi-channel cards on Windows systems don't use the standard Windows mixer interface and volume control, but instead supply a custom mixer application which Audacity can't hook in to. In these cases you need to select the recording settings and levels using the custom mixer application shipped with the soundcard. Recording should work as normal with the card however.

=== Recording Devices ===

In current Audacity select recording inputs at {{Menu|Edit > Preferences: Devices tab}}, in the {{Menu|"Recording Device"}} dropdown. In current Audacity, recording devices can also be viewed in [https://manual.audacityteam.org/o/man/device_toolbar.html Device Toolbar]. To enable this toolbar, click {{Menu|View > Toolbars > Device Toolbar}}.  
<div id="vista"></div>
 
===Windows Vista / Windows 7===
 
 
 
The most recent Windows operating systems called Vista and Windows 7 treat individual recording sources such as line-in, microphone and "stereo mix" as recording devices in their own right. As a result, the '''Mixer Toolbar input selector will be always be greyed out by default'''. Some users report that input sources can be made to appear in the input selector by running Audacity in compatibility mode for Windows XP. To do this, right-click over audacity.exe in Windows Explorer, then click Properties, then the "Compatibility" tab. This isn't a generally recommended solution. 
 
 
 
Instead, in current Audacity select recording inputs at {{Menu|Edit > Preferences: Devices tab}}, in the {{Menu|"Recording Device"}} dropdown ''(this dropdown is in the "Audio I/O" tab in legacy Audacity 1.2.x)''. Also in current Audacity, recording devices can be viewed instead in Device Toolbar. To enable this toolbar, click {{Menu|View > Toolbars > Device Toolbar}}. Here is an example of recording inputs in Preferences for two different physical devices (an inbuilt sound device and an external USB sound card):
 
 
 
Microphone: Realtek HD Device

{{Hint|1='''<center>HELP WITH RECORDING COMPUTER PLAYBACK OR STREAMING AUDIO</center>'''
 
There is often confusion over what source to use for recording sounds the computer is playing, and worse, this source is often hidden by default in the system mixer. The required source can go by various names such as: "Stereo Mix", "Wave Out", "Sum", "What U Hear" or "Loopback". The exact name (and even if you have such a source option) depends on the drivers of your sound device. '''Try to enable and select a suitable option in the system mixer as described below.''' Try [[Updating Sound Device Drivers|updating the sound device drivers]] if there is still no suitable source.
 
 
 
Sometimes "Stereo Mix" can only be made to work by using the control panel supplied by the sound card manufacturer - this is often reported with '''RealTek''' inbuilt sound devices. Try launching the sound device control panel from the Windows Control Panel or the system tray (by the clock). If you see a volume control for Stereo Mix, try clicking to select it. Confusingly, some RealTek devices "select" an input by muting all but one, so in this case, mute everything except stereo mix. If you don't see Stereo Mix, click the wrench icon and enable Stereo Mix in the dialogue that pops up. In some RealTek versions the option to check is '''"Enabled recording multi-streaming"'''. You should now see a volume control for Stereo Mix. Remember to select or unmute it as above. See this [http://forum.audacityteam.org/viewtopic.php?f=12&t=4485&start=0 Forum topic] for more help with RealTek. 
 
 
 
Be aware that on some machines, the "Stereo Mix" option will never work because it is disabled internally by the driver settings due to copyright concerns. This is a known issue with Lenovo Thinkpad laptops, but sometimes [http://forum.audacityteam.org/viewtopic.php?f=12&t=4485&hilit=realtek+stereo+mix+mute&start=10#p17657 editing the driver files] can enable stereo mix. 
 
 
 
If all else fails, you can connect a cable from the line-out (green) port of the computer to the line-in (blue), and choose the line-in as recording source.  If you need to hear what you're recording, you can buy a single stereo to double stereo adaptor that will give you a spare jack to plug the speakers into. Alternative suggestions follow below.
 
* [http://www.freedownloadsplace.com/Freecorder-Toolbar-Download-843.htm Freecorder 3.0] is a browser plug-in. It records to lossless [[WAV]] or lossy [[MP3]] format direct from the program producing the sound, without the need for a sound device that can record computer playback. Note that with newer web browsers or Windows Vista/7 it may be difficult to prevent Freecorder 3 upgrading to the latest version, which only records as MP3.

It is common on Vista and 7 that '''not all recording inputs are automatically enabled in the Recording tab'''. This means they are invisible in that tab, and also invisible to recording applications like Audacity. So you need to make them visible, then enable and make default the one you want to use, thus:
 
# Right-click anywhere inside the Recording tab and choose '''"Show disabled devices"''' then right-click again and check '''"Show Disconnected Devices"'''
 
# For a device having a physical input like line-in or microphone, connect the required cable and make sure it fits tightly - a physical device not connected may show as "currently unavailable"
 
# Right-click specifically over the input device you want to record with (for example, line-in or "Stereo Mix"), and if visible, choose '''"Enable"'''
 
# Right-click once again over the input device you want to record with, and choose '''"Set as Default Device"'''
 
# Right-click once again over the input device you want to record with, click {{Menu|Properties}} then the {{Menu|Levels}} tab and ensure the volume slider is turned up 
 
# Windows sound settings are often optimised for [http://en.wikipedia.org/wiki/Voice_over_Internet_Protocol VoIP] (internet calls) using programs such as [http://www.skype.com Skype], but these settings can interfere with high quality microphone recordings of music. Turn off all VoIP enhancements and any other sound effects unless they are essential:
 
## Right-click over "Microphone" and choose "Properties" then look for an "Enhancements" tab where you can '''"Disable all sound effects"''' (if necessary, also look in the "Levels" or "Custom" tabs and on the main "Playback" tab for unwanted sound effects)
 
## On Windows 7, click the "Communications" tab then under "When Windows detects communications activity:", choose '''"Do nothing"'''; this should prevent volume issues if recording computer playback or when recording over playback of another track 
 
#* If you do make extensive internet calls then it is probably desirable to right-click over the microphone and choose "Set as Default Communication Device".
 
# To prevent possible sample rate or recording channel discrepancies, right-click again and click {{Menu|Properties}} then the {{Menu|Advanced}} tab, and make sure the '''"Default format"''' matches both with the project rate bottom left of the Audacity screen, and with the number of "recording channels" in the '''Devices''' tab of Audacity Preferences ''(Audio I/O tab in legacy Audacity 1.3.7 or earlier)''; now click '''"OK"'''
 
# Click the Playback tab of Sound, right-click over the "Speakers" or "Headphones" device for your computer sound device and set it as '''"Default Device"''' or '''"Default Communication Device"''' as required; then right-click and click {{Menu|Properties}} then the {{Menu|Advanced}} tab, and set '''"Default Format"''' to match with the settings in Step 7 above.

<div id="linux_missing"></div>
 
===Entire Mixer Toolbar missing===
 
If Audacity's entire Mixer Toolbar (i.e. the input and input level sliders and the input selector) is missing, this usually means that the version of Audacity you have installed has been built without PortMixer support. This could be because your Audacity version was built wrong, or because it's using an (experimental) v19 version of [http://www.portaudio.com/ PortAudio] which hasn't got PortMixer support. If you click on <span  style="background-color: #CCFFCC"><font color="#a0522d">Help > About</font></span> in Audacity, you should find the version of PortAudio that has been used and a list of which libraries were enabled at build time.
 
 
 
To enable Audacity's Mixer Toolbar, you can either install from a package which has PortAudio v18 or compile Audacity from the [http://audacity.sourceforge.net/download/source source code] using PortAudio v18. For instructions on using the source code to compile Audacity, see [[CompilingAudacityForBeginners]]. 
 
 
 
If you want to compile Audacity with PortAudio v19 (which gives native ALSA support) and also want to have a Mixer Toolbar, you must use the current Audacity version. There may not be a 1.3.x package yet for your particular distribution, but you can compile Audacity from the [http://audacity.sourceforge.net/download/beta_source Beta source code]. If you want native ALSA support in legacy Audacity 1.2.6, you could compile it with PortAudio v19, but this is no longer supported, and means you will have to choose your input source and the input/output levels in ALSAmixer. 
 
 
 
<div id="linux_minimised"></div>
 
 
 
===Input Selector minimised, sliders present===
 
 
 
If the selector just appears as a small lump but you have the input and output volume sliders, this usually means that there is currently no audio device available to, or recognised by Audacity for recording on your system. There are various possible causes for this. They include:
 
 
 
# Another audio program like XMMS is using the sound device
 
# A sound daemon/server like esound (ESD), aRts or [http://pulseaudio.org/ PulseAudio] is using the sound device
 
# You have system sounds turned on in a desktop environment like Gnome or KDE
 
# You don't have the correct permissions to access the sound device
 
# You are using Audacity 1.2.6 and are selecting the ALSA device but don't have the necessary OSS emulation modules installed. 
 
# The recording device you currently have selected in the Audacity Preferences only has one input source, and so there is no choice that can be made. Many USB and Firewire Input/Output devices fall into this category.
 
 
 
So, there are three main points. Firstly, any other applications using the sound device must be disabled, unless you use:
 
 
* the  '''aRts''' daemon with the OSS device, in which case you can use the wrapper provided by aRts and run:<ul>{{code|$ artsdsp audacity}}<br>Note: some users report recording issues when doing this.</ul>
 
* A recent Ubuntu-supplied Audacity package including an '''alsa: pulse''' device. Otherwise, Audacity must be run with ''padsp'' to run PulseAudio with OSS, or ''pasuspender'' to suspend PulseAudio. Here is [http://www.pulseaudio.org/wiki/PerfectSetup#Audacity more information about Audacity and PulseAudio].   
 
 
 
Secondly, if you use OSS, you must check that /dev/dsp (the OSS device) is present.  If you use ALSA, you must install the OSS emulation for ALSA, unless you are using Audacity 1.3.x which supports ALSA natively.
 
*To load the installed OSS emulation modules for ALSA, you can launch Audacity from the command line as:<ul>{{code|$ aoss audacity}}</ul><br>
 
 
 
Thirdly, on many distributions you must add your user to the "audio" group to give them permissions to access sound devices.
 
{{Hint|Providing Audacity can successfully recognise the recording device in Preferences, you can always select input sources in [http://en.wikipedia.org/wiki/Alsamixer ALSAmixer], even if the correct source selection cannot be made in Mixer Toolbar, or if the input selector is not available.}}

Warning icon This page contains important information for users of current Audacity on Windows about enabling inputs in the Windows Control Panel.

Mixer Toolbar issues and input device selection

In current Audacity, all available inputs are selected in Device Toolbar or Devices Preferences.

Recording Device

It is often assumed that Audacity controls the input sources displayed, but in fact the sources offered are governed by the drivers of the sound device that is currently selected in the Audacity Preferences. Drivers are a big issue on Windows machines, and it often happens that machines purchased new will only be supplied with generic Microsoft drivers. This may prevent the audio device linking properly to the system mixer, so you may end up always recording from line-in, or cannot apparently record at all (whatever input source you choose). Another issue may be that you won't see all the inputs that your device potentially offers.

So the first step towards rectifying input problems is to open the Preferences and choose Devices . Find out what inputs are available and ensure that the playback and recording devices are explicitly set to the correct device you want to use. For example you may have multiple sound devices such as built-in sound and an external USB device, so you need to choose between them. If you are on Windows and experiencing problems, choose your sound device explicitly, not Microsoft Sound Mapper (which is intended to map to the currently selected default Windows sound device, but may not always do so correctly).

Bulb icon Note that on Windows 7 and later, initial driver setup typically disables all the inputs except for the built-in microphone. It is strongly recommended to use the Sound Control Panel to show and enable all disabled devices so that recording applications like Audacity can see them.

Device selection for inbuilt devices on Windows

Note that some sound devices have individual analog to digital converters (ADC's) for the different inputs such as microphone and line-in. Where this is the case, these inputs are treated as separate recording devices on Windows (for example, "Line-In: Realtek" or "Microphone: SoundMax"). These inputs can be most conveniently selected in Device Toolbar in current Audacity but in legacy Audacity before 1.3.13 they must be selected in the Audio I/O or Devices tab of Preferences and not in the Mixer Toolbar selector which will be greyed out.

Windows 7 and later always treat recording sources as separate "devices", so on these systems the Mixer Toolbar selector in legacy Audacity will be greyed out and inputs must be chosen in the Audio I/O or Devices Preferences.

USB and Firewire recording devices

Note that if your selected recording device is a USB or Firewire device, these normally do not have multiple input sources to choose from, so Device Toolbar or Preferences will only list the device as a single choice and the input selector in legacy Audacity will grey out. This is normal, and just means that input choices must be made in the device itself, or in any control software that comes with it. Examples of devices which will normally not allow input selection in Audacity are the Griffin iMic, USB turntables or USB cassette decks and a wide variety of USB and Firewire mixers and interfaces.

Multi-channel recording devices do allow limited input channel selection in Audacity where the drivers support this, though only a few devices on Windows allow recording more than a pair of two channels at once unless you compile Audacity with ASIO support.

Device already in use

Also check your sound device is not already in use. If you are on Mac or Linux and the sound device is already being used by another application, Audacity may not be able to access it for recording. As a result, Device Toolbar, Preferences or the legacy Mixer Toolbar input selector may be empty of devices. Generally, this is not a problem on Windows as long as you choose MME host in Audacity, though issues with some applications are known. For example, speech recognition in Word, Skype or the Fraps screen capture software may prevent other applications from using the sound device to record from a microphone.

Windows Problems

Warning icon We strongly suggest you obtain the current version of Audacity then read our further information about Windows 10, Windows 8 and Windows 7.

Card Not Supported

Some high-end multi-channel cards on Windows systems don't use the standard Windows mixer interface and volume control, but instead supply a custom mixer application which Audacity can't hook in to. In these cases you need to select the recording settings and levels using the custom mixer application shipped with the soundcard. Recording should work as normal with the card however.

Recording Devices

In current Audacity select recording inputs at Edit > Preferences: Devices tab, in the "Recording Device" dropdown. In current Audacity, recording devices can also be viewed in Device Toolbar. To enable this toolbar, click View > Toolbars > Device Toolbar.

If selecting a particular input does not work, or you don't see the input you want, try selecting it in the Windows Control Panel (see the next section below).


Accessing the Windows Sound controls

See Windows: accessing the Windows Sound controls in the Audacity Manual for full details - this former Wiki section has been transferred there.

Bulb icon Accessing the Windows Sound controls and trying to select your required input there may often allow you to record into Audacity, even if the input you want isn't in Device Toolbar or Devices Preferences, or isn't recording properly.
