There are hundreds of different Realtek HD-audio codecs and we can't
put all in the driver names :) Basically the driver is for ALC882 and
its compatible codecs.

Your problem is rather specific to Realtek codec, so it's only about
CONFIG_SND_HDA_CODEC_ALC882. I'm not sure what made Linus' system
broken, but my wild guess is that the lack of specific HDMI codec
support caused the user-space side configuration mismatched somehow.
