To start somewhere, what type of playback/recording do you want to work? As in, what sample format, what number of channels etc? Looking at stereo playback for a start, it looks like the driver's hardware parameters does not allow setting the number of channels to "2": D: [pulseaudio] alsa-util.c: Trying hw:1 with SND_PCM_NO_AUTO_FORMAT ... D: [pulseaudio] alsa-util.c: Managed to open hw:1 D: [pulseaudio] alsa-util.c: snd_pcm_hw_params_set_channels(2) failed: Invalid argument Do you have a working "aplay -v" setup to compare with? -- David Henningsson, Canonical Ltd. https://launchpad.net/~diwic
