I tried mainline daily build 6.9.0-060900rc4daily20240420-generic.
(Does it include commits that came a few hours before?) The microphone
appears to be an acp63 device. Both snd_pci_acp6x and snd_pci_ps are
loaded. Is the next step to blacklist snd_pci_acp6x?

Title:
No input through internal microphone (Ryzen 6000)
Status in linux package in Ubuntu:
New
Bug description:
The microphone in a Thinkpad P14S (AMD) Gen 4 stopped working after
updating from 23.10 to 24.04 Beta with kernel 6.8.0-22-generic. This
is a known problem and a patch may be included in kernel 6.8.3.
Is it possible to backport this patch? Or is the plan to wait for a
kernel update? It would be good use the microphone in 24.04.
The symptoms are exactly as described in
https://bbs.archlinux.org/viewtopic.php?pid=2162297#p2162297
Reportedly the patch is included in
https://github.com/zen-kernel/zen-kernel/blob/6.7/main/sound/soc/amd/yc/acp6x-mach.c#L59
