If you’re willing to live without audio until a fix is released, you might try disabling the Smart Sound Audio Controller. Note, though, that this is contingent upon my diagnosis being correct. 
At least on my machine, this unloads the driver that seems to be causing the failed power state transition:
# sc query intcaudiobus
SERVICE_NAME: intcaudiobus
TYPE : 1 KERNEL_DRIVER
STATE : 1 STOPPED <-------
WIN32_EXIT_CODE : 31 (0x1f)
SERVICE_EXIT_CODE : 0 (0x0)
CHECKPOINT : 0x0
WAIT_HINT : 0x0
However, it might require a reboot to release any other resources it was holding.
