Hi Amadeusz,
Yes, I did the bisects using
https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/

The only thing I did to these was add
392cc13c5ec72ccd6bbfb1bc2339502cc59dd285, otherwise audio breaks with
the dai not registered error message in dmesg from the rt5514 bug from
6.0 and up. It wasn't added to 6.1 until rc6, I believe. If there's a
better way to work around the multiple bugs I can try again, otherwise
I will start working on builds from tags and see if I learn anything.

FWIW, I've seen two people complain that Arch isn't working either
since it moved to 6.1. For the one who was trying, patching out the
commit I came to with the first bisect did not regain them sound like
it did for me. And yet Sasa reports Slackware is mostly working for
him with 6.1.8 on Slackware. I don't know what to make of it, but
thought I'd share in case it helps point someone else to something.

Probably less relevant since they aren't from upstream and I know they
don't mean as much, but I have tried 6.1.5-6.1.8 Fedora packages for
certain, and went back trying several others from koji back into rc
builds, although using prebuilt kernels, anything before 6.1-rc6 won't
work, as mentioned above. Nothing worked. But as I said I'll build
from tags and see if I can learn anything.

Thank you,
Jason Montleon
