Audio playback no longer works after after upgrading to linux-6.17.1.arch1-1 and rebooting (wpctl status returns an empty audio sink list). I've briefly checked the kernel release notes, but can't tell if this is an issue with a driver or something that I can fix

More info about my setup

$ lspci | grep Audio
00:1f.3 Audio device: Intel Corporation Comet Lake PCH-LP cAVS

Does the audio interface come back after you downgrade to 6.16?

sudo pacman -U https://archive.archlinux.org/packages/l/linux/linux-6.16.arch2-1-x86_64.pkg.tar.zst

This is most likely a kernel regression, which should be bisected and reported to the upstream kernel developers

Are you confident to do the bisection on your own or do you need some help?
If you want we could also provide you with pre-built kernel images for you to test (which greatly speeds up the test time)   a
