Sound issues with ALC4080

[Patrick Quoika]

First of all apologies, if I misplaced this bug report, but I did not know where else to put it...

I am experiencing some issues with the ALC4080 sound card on Ubuntu 20.04.4 LTS.

I do not get any sound from the front jack (headphones). This is actually an issues that may be found on google as well.
From the back jack, I do get sound output, but it is somewhat distorted. It is hard to put it into words, but I would describe it as just very slighted slowed down and distorted towards bass-heavy.

If I play sound via the graphics card (hdmi port to nvidia graphics card), the sound is absolutely normal. I may also plug in the headphones to the screen, which receives the hdmi output and the sound is perfectly fine.

I guess the issue is somehow connected to the ALC4080 being some weird USB-audio interface, but I do not understand much about these matters.

I am not sure, which packages shall be made responsible for this problem...

`apt-cache policy pulseaudio`
returns
```
Installed: 1:13.99.1-1ubuntu3.13
Candidate: 1:13.99.1-1ubuntu3.13
```

`cat /proc/asound/version`
returns
`Advanced Linux Sound Architecture Driver Version k5.13.0-39-generic.`
