ALC4082 - ASRock Z790 PG-ITX/TB4

[Shmob1]

I have an ASRock Z790 PG-ITX/TB4 which has the ALC4082 Realtek chipset connected over USB, that has been mentioned in a number of issues, most recently #229.

It seems the configuration changes in that issue (notably, hwchong@3ec7e6e) work on my board as well, with a small modification. Unlike the Taichi boards, my Realtek audio driver is at USB26ce:0a08, not USB26ce:0a06. Making the necessary regex changes in ALC4080-HiFi.conf and USB-Audio.conf enables functionality on my board.

I am happy to make a PR to merge these changes if pertinent.

Thanks for the great work!

Update:
I am unable to get more than 2 channels through spdif either using AC3 or DTS
