Comment # 9 on bug 1161367 from Takashi Iwai

Glad to hear you found a workaround, and no need for apology.  A bug report is
always good.

And judging from the alsa-info.sh output, it might be related with the new
codec, and hopefully it's supported better now with a newer kernel.

You can try the kernel in OBS Kernel:HEAD repo at any time while keeping the TW
kernel as is.  It's a good feature of multi-version installation.
It's already 5.5-rc7, so mostly stable, I'd say.

If you find the same problem with 5.5 kernel, feel free to reopen (or open
another report) for tracking the problem again.  Thanks.
