The "-c 1" was simply wrong. The default (-c 0) sound device of older kernel / alsa has a numid=3 selector for auto vs headphone vs hdmi . Newer kernel simply has multiple devices. Also, headphone is -c 0 . $ amixer contents numid=2,iface=MIXER,name='Headphone Playback Switch' ; type=BOOLEAN,access=rw------,values=1 : values=on numid=1,iface=MIXER,name='Headphone Playback Volume' ; type=INTEGER,access=rw---R--,values=1,min=-10239,max=400,step=0 : values=-2000 | dBscale-min=-102.39dB,step=0.01dB,mute=1 TODO: For now, broadly dividing by kernel v4.x vs v5.x is good enough, but it would be nice to find out when / which kernel /alsa this is relevant. closes https://github.com/respeaker/seeed-voicecard/issues/240
