I encountered this debug output when running the sound test from System/Preferences/Sound:
Jun 19 10:38:26 lanai kernel: [ 19.488000] ALSA sound/pci/hda/hda_intel.c:556: hda_intel: azx_get_response timeout, switching to polling mode...
I also tried 'nomsi' as a kernel boot parameter with no audible difference.
