USB-microphones are usually setup as /dev/dsp1 under Linux.

The stable version of Audacity will not find /dev/dsp1 unless there is also a device called /dev/dsp0. (This is a bug in PortAudio that should be fixed in a future version.)

To work around this bug, try setting the AUDIODEV environment variable (at a terminal):

    $ AUDIODEV=/dev/dsp1 audacity

or try running

    # ln -s /dev/dsp /dev/dsp0

as root. Please let us know whether this helps or not.

It is also possible to run Audacity through an ALSA emulation layer, with:

    $ aoss audacity

which should enable audacity to use ALSA-devices natively.

Samson C01U USB-microphone

There are apparently some issues with using the Samson C01U USB-microphone under Linux. There are some documents outlining the problem:

• First post (although with not entirely correct assumptions under the "Bad news" heading)
• Follow-up
