[Bug Hunting] ALC892 audio stuck

[yukiteruamano]

Hi, right now I have a workstation with Ryzen 7 3800x, B550 Motherboard and a audio codec Realtek ALC892.

From my first installation the only issue with OpenBSD is audio random stuck, a old problem with Realtek Audio and Ryzen PC not solved.

In my hunting a test two awful patch in azalia_codec.c and azalia.c, source code files, and the problem remain but a sligth improvement.

The audio stuck without patch, take place in few minutes (and generally less a hour playing music), but with patch, I have now 22 hours continous playing music without problem but finally, the audio stuck again.

This is a not a definitive solution but is a improvement...my intention is resolve problem but I need help, ideas and testing.
