Created attachment 1882045 [details] logs From the 5.17.7 kernel the microphone doesn't work anymore, nothing I tried makes it work again. I need to boot with the 5.17.6 kernel for it to work properly. I use a JBL T205 headset
I'm seeing this too, but with various 5.17 kernels. I've tried 3 different systems and the 5.16.20 kernel works fine but with the 5.17 kernels I get dropped words/sentences, static, etc. I'm testing with Zoom, a Plantronics 5220 headset, and Panasonic wired earbuds. There are occasional messages like this for the Plantronics headset under 5.17.6: May 23 13:44:43 draco kernel: usb 1-1.4: Warning! Unlikely big volume range (=1024), cval->res is probably wrong.
I forgot to mention that I'm on F35, on a Dell Optiplex 7010, a Lenovo ThinkPad, and a HP DC7800.
I'm on Fedora 36 and the internal microphone of my laptop stopped working. I also tested briefly booting a previous 5.16 kernel, and I got the impression that the microphone did not work with that kernel as well any more.
I did some more testing. I booted the oldest kernel I have still available. That is 5.17.6-300.fc36.x86_64. I have the problem with that kernel as well. Here is a list of dates of kernels that I have on my system: -rwxr-xr-x. 1 root root 11798960 May 9 18:05 vmlinuz-5.17.6-300.fc36.x86_64 -rwxr-xr-x. 1 root root 11800752 May 12 17:30 vmlinuz-5.17.7-300.fc36.x86_64 -rwxr-xr-x. 1 root root 11803056 May 16 03:21 vmlinuz-5.17.8-300.fc36.x86_64 I am sure that the microphone worked still well yesterday morning (23 May). I did apply system updates yesterday, but I forgot if this was before or after my video call. Anyway, I think that this bug is not directly kernel related, but that one of the recent updates broke the microphone. I tried to find which packages might be the culprit: # dnf history info 1724 | grep alsa Upgrade pipewire-alsa-0.3.51-2.fc36.x86_64 @updates Upgraded pipewire-alsa-0.3.51-1.fc36.x86_64 @@System Unfortunately, I did not manage to do a dnf history rollback to see if going back before this update would solve the issue.
In GNOME settings, I do see the microphone working (I see the red bars moving when speaking, see screenshot), but in gnome-sound-recorder (Sound Recorder) the input sound indicator is flat. As a test I reverted to pipewire-alsa.x86_64 0.3.49-1.fc36, but that did not solve anything.

For voice recorder it recognizes it but for the system it doesn't.
I discovered that the microphone does work with Signal, that I installed as a flatpak. However, with GNOME Sound Recorder, and Microsoft Teams (also installed as a flatpak) the microphone does not work.
One of the systems I'm having trouble with was upgraded from F34 to F35 in mid-April and it still had some F34 kernels on it. I booted F34 5.16.17 and it worked better in that the things I was saying were not cut off or dropped entirely. There was background noise/static though. Two of the systems are dual boot Win 10/Fedora 35 and the microphone works fine in Windows but not in Fedora so that probably eliminates the hardware as the issue. On another system I reverted to pulseaudio from pipewire but that didn't help - still dropped words/sentences.
This issue "resolved itself" for me. The microphone is working again. This probably happened after some updates.
