Why do you want that? I mean, what are the two simultaneous things
you want to listen to, one comming from your game console and one
from your workstation?

That's not poor quality of the mainboard,
that's an electronic device suffering a _lot_
of interference from the electronics jungle around it.
> When switching to SPDIF the noise is gone
Yes: the digital signal does not suffer from the analog noise.
Does you headphone amplifier take the spdif output of your workstation?
(What headphone amplifier is that?)

Meaning, you still hear the sounds that your workstation produces,
but not the sound your gaming console sends to your line-in?

I see no record.mode in the mixerctl settings.

Your mixerctl says it's an input.
> mixerctl -a
mixerctl -av might be more telling.
