Hello Christian,
Thank you for report! Issue is a known one to us and has already been
addressed by:
[PATCH v4 00/13] ASoC: Intel: Catpt - Lynx and Wildcat point
https://www.spinics.net/lists/alsa-devel/msg113762.html
waiting for final dependency to be merged (Andy's resource-API
changes, as Mark already added the SPI ones) so v5 with review changes
can be provided. Shouldn't be long before this gets merged. As
consequence, /haswell/ ceases to exist.
That leaves people with no working sound for 5.8 and 5.9.
Basically, once power-cycle (D0 -> D3 -> D0 transition flow) had been
fixed, more - previously hidden - problems arisen. Instead of sending
70+ patches to Mark refactoring existing code to recommended flow (+
readability and performance improvements), replacement is provided
along with old code being removed entirely.
For now, if there's a possibility for you to modify your kernel, said
patch can be safely removed from your local repo. Note: following is
the outcome:
- DMA init may occasionally fail on early boot (audio card won't be
present at all, requires reboot)
- D0/D3 flow doesn't follow recommended sequence and thus power-saving
may be limited or non-existent
Probably still better than permanently fuzzied audio..
Doesn't this mean that a revert is needed and applied to -stable for 5.8
and 5.9?
I believe you're right Pierre, revert should be provided. I'll see to it.
