Hi everyone, Takashi Iwai suggested that I test OBS home:tiwai:bsc1219789 repo. His comment suggest he reverted commit c3ab23a10771bbe06300e5374efa809789c65455 ASoC: amd: Add new dmi entries for acp5x platform. My audio seems to work again

Now I'm building a test kernel with the revert of the suspected backport patch. It's being built in OBS home:tiwai:bsc1219789 repo. Please give it a try later once after the build finishes (takes an hour or so).
So the culprit was the stable commit 4b6986b170f2f23e390bbd2d50784caa9cb67093, which is the upstream commit c3ab23a10771bbe06300e5374efa809789c65455 ASoC: amd: Add new dmi entries for acp5x platform
On the other note, I am not the recipient of your reply email Ciao, Thorsten. I had to grab the emails from the MAINTAINER list.

Hi kernel maintainers,
I noticed 6.7.4 has introduced a regression for the steam deck. The LCD steam deck can no longer probe the acp5x audio chipset anymore. This regression does not affect the 6.8.x series. I did not test kernel 6.7.3 because Opensuse tumbleweed skipped the update on my machine.
Steps to reproduce the problem
- Obtain a steam deck
- Install kernel 6.7.4
- Boot the device and you will see dummy output in gnome shell
Observed kernel logs.
