Can you get any kernel messages or stack trace?

I think all of these come from the codec communication error.
The ca0110 parser part hasn't been changed for long time. IIRC, the
regression occurred at time we introduced the multi-codec check.
The relevant changes begin with the commit
ALSA: hda: track CIRB/CORB command/response states for each codec
It'd need a bit tricky to revert all these without conflicts,
