Hi All, This bug got filed against Fedora last night: https://bugzilla.redhat.com/show_bug.cgi?id=1879277 "1879277 - Audio ducking after Linux kernel 5.8.8 update, with headphones plugged in" The system in the bug is using a MSI X570-A PRO motherboard. So this is almost certainly (this has not been confirmed) caused by commit 8e83bd51016a in the stable tree: "ALSA: hda - Fix silent audio output and corrupted input on MSI X570-A PRO". I'm not sure how to proceed with this one for the stable series, I guess a revert is in order, but that may (re)break non headphone usage? Takashi, do you have any suggestions? For more info please directly contact the reporter through bugzilla. Regards, Hans
