CMedia ... told me that the chips are different
The CM6610/20 chips did not get an updated -A version, so it's possible that the changes are just for the I²S I/Os, which should not affect the USB interface. Maybe the newer chip just gave them an opportunity to update the firmware.
there is a sequence problem between setting sample rate and sending the "play' command.
This sound like the interface setting problem fixed by this patch.
Something about UAC1 method not being the same as UAC2.
But this might indicate that we need to kick the Clock Source Entity.
