Yeah, it works!! Thank you very much. So in order to make aplay work I need to set all of these? -------------------- amixer sset 'HeadsetL Mixer AudioL2' on amixer sset 'HeadsetR Mixer AudioR2' on amixer sset 'Headset' 2 amixer cset name="DAC2 Analog Playback Switch" 1 amixer cset name="DAC2 Analog Playback Volume" 12 amixer cset name="DAC2 Digital Coarse Playback Volume" 2 amixer cset name="DAC2 Digital Fine Playback Volume" 50 -------------------- And what should I set making arecord also work? Sorry for that because I didn't have any alsa experiences.
