> Actually, I had updated one, but since you've already applied it - please
just remove "analog-surround-40" section from there, it doesn't work
properly with this card and basically can be replaced with 5.0 that works
fine for whatever reason.
> There are also remaining issues with this card, for instance, microphone
works only with 2.0 speakers mode, 2.1 and others are not compatible with
it currently (when selecting mic speakers resets to stereo).
> There was few threads with Raymond Yau, but we didn't figure out how to
fix it completely, please, take a look if you'll have some time.
It is a design limitation of pulseaudio, as the developer want to limit
the type of item in capture source exclude stereo mix,....,
it won't use snd_mixer_selem_get_enum_item() to get the current selected
enumerated item for the given mixer simple element
This mean that the capture source is alway unknown , it depend on
application UI pick up arbitrary item in the list as the active port
