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

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"
