alsa-project/alsa-ucm-conf issue #404 was edited from pinkflames:

While testing Torvalds' master branch of Linux which will become 6.9-rc1 eventually, I have stumbled upon PipeWire/WirePlumber apparently no longer applying the UCM profile for my USB connected on-board audio controller. Git bisection leads to the following commit: torvalds/linux@1601cd53c7e3197181277326dbfc131d20a74e46 . It's possible that I'm wrong in concluding that the issue is UCM no longer applying/matching but that's my best guess looking at seemingly ACP named devices and the lack of any `ucm` strings in the output of pw-dump, when the regression is present.

Since this is likely a kernel regression, I'll be reporting that to the [kernel bugzilla](https://bugzilla.kernel.org/show_bug.cgi?id=218605), too, but I thought alsa-ucm-conf might be interested in this change as well.
