I tried again on kernel 5.3.12-2 and keys also does no work. Maybe something fishy in the BIOS, i will check it further. -- You are receiving this mail because: You are on the CC list for the bug.

I'm not entirely sure whether it's a breakage in the kernel, though. It might be some changes in the user-space side (e.g. udev, which usually maps some media keys via hwdb, see /usr/lib/udev/hwdb.d/*). You can try evtest for checking the raw input device events, too. -- You are receiving this mail because: You are on the CC list for the bug.
