Arch Linux

No sound after kernel update 5.1.6 -> 5.2.7 / 5.2.8. I think sound card is not even detected. Works fine after downgrading back to linux-5.1.6.arch1-1.

Don't know if related, but gnome desktop starts working more slowly / freezing as well.

It's a hp spectre x360 13-4002ne laptop.

I attached output of `journalctl -b 0 -p 3` for errors which I think are relevant. I don't think ACPI errors are related as I had them before.

I also tried it with linux-mainline kernel from AUR (5.3.0-rc3). Did not fix it. Attached journal output for that as well, because there is one additional error there.

I suspect this might be related to the inclusion of open sound firmware with 5.2.x: https://kernelnewbies.org/LinuxChanges#Linux_5.2.Inclusion_of_Sound_Open_Firmware

Some other outputs while running 5.2.7:
