Howdy! I am trying to get a livestreaming setup where I can hear my
microphone and line in at the output (zero latency monitoring) and also
record the stereo mix (record what I hear). I have achieved this on
Windows, so I know the hardware can do it, and now I'm trying to achieve
this on linux. When I configure it on windows, the stereo mix appears as
an extra input.
I've managed to get the monitoring to work, but can't manage to record
the stereo mix.
I've tried various combinations of flags in the hint file, sometimes I
can see Stereo Mix as the source for the two DACs, and sometimes not.
When I select it, there is no signal coming in, even though I'm playing
some sounds.
I am not sure what to try next. I don't understand what pins are, I've
tried hda-analyzer and it's not clear to me what flags I need to set.
Maybe I can take the config from windows and copy it to linux somehow?
Is there a driver flag that creates the stereo mix as an extra input?
I don't want to use software options like using the pulseaudio monitor
source, because that wouldn't have the mic mixed in, and I want to
monitor the mic volume relative to the desktop volume, essentially to
record what I hear exactly as I hear it.
Thanks in advance!
