[alsa-info](https://alsa-project.org/db/?f=eca30fae9c2bfca031f9cc921462dd7bc864d8fb)

I'm not too familiar with the audio stack to really make a fix.
>From my small investigation, it seems like there is no UCM for my card:
```
~ cat /proc/asound/cards
 0 [NVidia         ]: HDA-Intel - HDA NVidia
                      HDA NVidia at 0xd0080000 irq 128
 1 [Generic        ]: HDA-Intel - HD-Audio Generic
                      HD-Audio Generic at 0xb02c8000 irq 129
 2 [Generic_1      ]: HDA-Intel - HD-Audio Generic
                      HD-Audio Generic at 0xb02c0000 irq 130
```

My issue is that audio control from KDE is borked.

Instead of just adjusting the PCM volume, it adjusts the master, then the speaker, and then the PCM.
Other knobs seem to do no useful work, except the speaker balance (AMP1/AMP2).

(also, I'm not sure that master and speaker actually do what they are named; they both seem to just make the sound "dull")

I can clone repo, test PR & etc.

Thanks.
