Public bug reported:
I have a MSI MAG X570s Torpedo MAX motherboard, which has an onboard
'Starship/Matisse HD Audio Controller' controller that has a weird
mapping via USB audio (see bug:
https://bugzilla.kernel.org/show_bug.cgi?id=206873 for a similar
configuration).
Sound via line-out works fine without any interventions.
Headphone output however does not, while Ubuntu correctly detects the
headphones as being plugged in when selected sound is still output via
line-out, instead of via the front panel headphone jack-out.
After some debugging I figured the headphones are connected to a seperate Alsa
device on the same card as the line-out.
Running 'pacmd load-module module-alsa-sink device=hw:2,1' gives me a working
audio output that plays just via the headphone out.
I guess a quirk needs to be written for the configuration.
