This bug is awaiting verification that the linux-oem-5.14/5.14.0-1046.53 kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-focal' to 'verification-done-focal'. If the problem still exists, change the tag 'verification-needed-focal' to 'verification-failed-focal'.
If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed.

And for Jammy kernel, this SRU depends on #1949245, after merging the patchset for #1949245, then could apply this SRU to jammy. [Impact] On the AMD YC platforms, the internal mic can't be detected and there is no internal mic for users to use. [Fix] Backport 2 patches from mainline kernel to fix this problem. [Test] boot the patched kernel on the machine which has updated BIOS, after loging into the desktop, open the gnome-sound-setting, there is internal mic, and could record sound via internal mic. [Where problems could occur] This only impacts intenal mic detection on AMD yc machines, it will check the acpi variable first, if not detected, it will check the acpi dmi table as before, so the regression possibility is very low, and we already tested these patches on a couple of Lenovo YC machines, all worked well.
