USB mic on Linux

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.
