Then the message is a red herring.

This proc file looks fine.  You don't hear from the headphone but from
the line-out jack, right?

To be sure, get the codec proc files before and after the problem to
compare.  (lspci register dump might be worth to check, too.)

Then I have no certain clue what could be a culprit yet now.  The
symptom sounds like the DMA stops working by any reason, but this is a
pretty uncommon case.  Usual hda-intel bugs are about the wrong mixer
setting or routining, or the communication errors between the
controller and the codec chips.  You'd have to see other error
messages in such cases.

It might be related with the power management...
