(CCed to -multimedia after some time with no answers on -questions)
I have the snd_hda driver which creates /dev/dsp0.0 and /dev/sndstat but
I get no sound when I do cat /bin/sh > /dev/dsp0.0.
I know I need to change device hints etc. but I'm not sure to which ones.
/dev/sndstat attached with verbose level 3
