The patch below does revert conditionally only for Intel controller chips. This should work instead of git revert. Let me know if it really works for you.
Indeed t works.
OK, I queued the fix, with Cc to stable now.
But, we still want to understand why. Maybe assigning the device manually to an explicit value and figuring out which dev# doesn't work would be helpful.
How do you want me to test this?
Specify directly the stream number assigned to a PCM playback. Change dev to a different value, and see whether it works while keep nums = 1. dev = 0 is reserved for the capture stream, so use other values.
Test this only with onboard analog, and better to avoid PulseAudio. Fixated numbers would break HDMI audio badly.
