Thanks. 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?
