I see this behavior on three different computers. Rebooting into an old enough kernel gets things working again. The older kernels also have older initramfs images. I could rebuild those to see if there is some issue there instead of the kernels themselves?

I tested one of the older kernels (where the headset still worked) with a rebuilt initramfs and the headset still worked. So it likely isn't an issue with something in the initramfs images.

Can you revert commit e9ba389c5 ("ALSA: usb-audio: Fix scheduling-while-atomic bug in PCM capture stream") and see if that helps? If not, can you summarize again which kernels still work for you and which don't?
