alsa-project/alsa-ucm-conf issue #598 was opened from LuanVSO:

hi, i had a problem where opening the kde plasma volume applet would make the volume on my headphone jump to the maximum.
after muting the "PCM 2" channel on alsamixer i notice that the volume on the headphone would go muted instead.
so i edited the ALC4080-HiFi.conf file and remove every mention of S/PDIF and rebooted my machine.

after the change the problem didn't happen anymore.
what do you need to fix the mapping problem?

i think this happens because the "PCM 2" volume controls is redirecting to headphone output, but it doenst have a slider, so it is either max or muted:

(also the S/PDIF aways appeared as connected even though i did not have anything connected to it, don't know if it is expected)
