You either need to write a PulseAudio profile or an ALSA UCM configuration file to tell PulseAudio about the ALSA devices/mixer controls it needs to use to set up the device. Some documentation: PulseAudio profiles: http://www.freedesktop.org/wiki/Software/PulseAudio/Backends/ALSA/Profiles UCM configuration: http://git.alsa-project.org/?p=alsa-lib.git;a=blob;f=include/use-case.h and http://gitorious.org/omap-audio/audio-test/trees/master/ucm/Panda Regards, Arun
