Hi,
My build in speaker just stop working after update kernel from 6.9 to 6.10 (Fedora 40).
I faced this problem before: sound works on 6.8 but after updating to 6.9 it stopped working. After searching & trying fixes I found on the forums and none of them worked, I have to reinstall Fedora.
This time it is weird as it is working fine after several updates but stop working today (kernel update from 6.9 to 6.10). I can reinstall fedora again to make the sound work but I want to find a proper way so that it won’t happen surprisingly like this again and again.
FYI, right after install fedora, I follow this patch to fix the low sound level issue
