There is a second commit with a similar problem and really the one I should have linked; this one is much more severe.
Here is that fix: https://github.com/torvalds/linux/commit/37bee1855d0e3b6dbeb8de71895f6f68cad137be It also came into 6.8.3. 3e52444ed190 ("ASoC: amd: yc: Revert "add new YC platform variant (0x63) support"") Maybe you can try some of the mainline PPA builds to confirm they picked up the fix. https://kernel.ubuntu.com/mainline/ -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/2062412 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 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2062412/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
