To make sure that ALSA can use the USB-mic in OSS-emulation mode, do a:

In the top row, (Bus 001 Device 004: ID 17a0:0001) is the USB bus number. Search for the lines which contains Audio and Control Device like in the screendump below:īDeviceClass 0 (Defined at Interface level)
If you see the mic detected, check for Driver= to see which USB-driver has been loaded for the mic.ĭisplaying a thorough list of USB-devices is done by issuing the command The latter has some example straightforward steps for compilation on Ubuntu Natty.Īnd search for the name of your microphone in the output. If you have issues trying to compile Audacity from source code, take a look at Developing On Linux and Compiling Audacity Step by Step Guide.

To get the most out of trying this, download the latest development source code from SVN and optionally, the latest version of Portaudio from. Which should enable audacity to use ALSA-devices natively.Ĭurrent Audacity (and legacy 1.3 series) has native support for ALSA devices using the Portaudio v19 library. It is also possible to run Audacity through an ALSA emulation layer, with: Please let us know whether this helps or not. To work around this bug, try setting the AUDIODEV environment variable (at a terminal):Īs root. (This is a bug in PortAudio that should be fixed in a future version.) The 1.2.x version of Audacity will not find /dev/dsp1 unless there is also a device called /dev/dsp0. USB-microphones in OSS are usually setup as /dev/dsp1 under Linux. 1.2.x versions of Audacity only support the older OSS (Open Sound System), but can work with ALSA using an OSS emulation layer. Current Audacity provides native ALSA support. On Linux, recording with a USB microphone is best done under ALSA (Advanced Linux Sound Architecture).
