Too bad, what do you intend to do about it?

I'd like to report a bug. But I don't what info is needed for that.
Now I'm on 5.3.10. Will wait 5.3.12.

Read the documentation in kernel sources which usually contains also the email of kernel driver developer. Then email the author and report your problem.

If possible, please try to identify the specific commit in 5.3.11 that broke this support. That is often helpful in determining how to fix it, and if no fix is obvious, it tells the maintainers what commit to revert to undo the regression.

I wrote to Takashi Iwai, who made most of commits to ALSA in 5.3.11.

What came of that conversation? I see you marked the thread as solved, but I can't tell from the posts here what solution you settled on. Did the author queue up a fix? A revert? In which kernel release(s) should we expect to see the problem resolved?

As I wrote earlier I'd written to Takashi Iwai about the problem.
He sent patch, that patch didn't work. Then another patch that worked, but there were errors.
Then more another patches and reboot, and finally working patches and no errors.
I wrote him about it but there was no reply.
