I am having trouble with my microphone lately. It used to work but at some point last week (cannot pinpoint the exact date) it stopped being recognized in all applications. I am fairly confident it is due to software upgrades, but I cannot tell for sure because I haven’t been able to figure out how to roll back kernel patch versions without compiling the kernel myself (which I’m not willing to do at this point).
My laptop is a relatively new Lenovo ThinkPad E14 Gen 6. When I got it, the microphone was initially not working because it needed an entry in the infamous “quirks table”. When this commit was released, I updated the kernel and the microphone started working just fine. But when I had a meeting this week, my meeting partners reported they saw my mouth moving but no sound coming through. I can hear them, so my sound output is working, but they cannot hear me.
I have been able to determine the following:
- My sound output (built-in loudspeakers) continues to work perfectly. During all this time, I never had any issues with sound output, including right away when I initially purchased the laptop.
- It definitely isn’t a hardware defect. On a dual-booted Windows on the same laptop, sound recordings and meetings are working just fine.
- I looked through the BIOS and could not find any option that might disable the microphone on BIOS-level. (Also see my previous remark about Windows working fine)
- The Fn-key for muting the microphone during OS runtime is detected and it “correctly” toggles the strike-through-microphone icon in my notification bar. But that doesn’t change anything because the microphone isn’t even detected in any applications in the first place, no matter whether the icon indicates it’s on mute or not.
Unfortunately, my expertise at debugging sound ends quite abruptly, so I came to this forum looking for help. Below, I am posting a bunch of diagnosis command outputs. If you know any advice, please point me in the right direction or tell me what else I can do to remedy this issue.

This tells me that the “quirk table” (linked in my explanation above) is supposed to detect and apply the patches for my microphone, as the 21M3 clearly matches.
The patch is also definitely released in my currently running 6.12 LTS kernel, as per linux/sound/soc/amd/yc/acp6x-mach.c at v6.12 · torvalds/linux · GitHub
