[Bug 2085082] Re: Cannot detect audio sinks and sources in proposed kernel

Since this is not fatal (in the sense that one can detect no audio when
the hw is affected and temporarily revert back to boot the old kernel) I
want to still release the new kernel (both Jammy GA and Focal HWE). And
apply the revert to the next security cycle which will release in 2
weeks. This is to not leave those kernels behind too long or delay the
next cycle.

Bug description:
[Impact]

Failed to detect audio sinks/sources.

[Test Case]

1. run "pactl list sinks short | grep -v -E "monitor|auto_null" to check if any sinks was found
2. run "pactl list sources short | grep -v -E "monitor|auto_null" to check if any sources was found


[Verify]

1. reverse the kernel to 5.15.0.124
2. run the same tests
3. confirmed audio is activate


[Fail rate]

3/3


[Expected result]
