[alsa-devel] Questions about Multi-streaming playback with HDA codec ad1988

[Raymond Yau]

it is strange that only this adi HDA  codec does not has "stereo mix" as
input source while the other adi codecs support stereo mix  ?

The "stereo mix" and "HD Audio Front Headphone" are available in SoundMax
Control Panel

it is also strange that I need to unmute "Analog Mix" in addition to those
"Mic Playback" and "Line Playback Volume"
