Upon further fiddling, I discovered that the issue is with alsa failing to correctly detect my USB webcam (Logitech V-UAX16) and timing out. Removing the camera fixes sound. However, this is still a definite regression. Can submit more data if that helps? https://git.kernel.org/cgit/linux/kernel/git/tiwai/sound.git/commit/sound/pci/hda?id=ea9b43addc4d90ca5b029f47f85ca152320a1e8d
