For testing, I passed single_cmd=1 as a modules option. HDAudio_03.pdf says, "If implemented, these registers must not be used at the same time as the CORB and RIRB command/response mechanisms, as the operations will conflict." Plus, if the RIRB irq is enabled, the interrupt routine will print out a spurious interrupt message. That said, my hardware is switching to single_cmd eventually, even if not passed as a module option. But at least now, when that happens my audio isn't dead.
