Sure Takashi, here you are:
------------------ This patch is adding extensive support (beside standard usb audio class) for Audio Advantage Micro II usb sound card. Features included: - Access to AES bits (so now sending the IEC61937 compliant stream is possible). - Mixer SPDIF control added to turn on/off the optical transmitter. ------------------
Best, Przemek

The changes look OK to me, but the patch description is completely missing. Please give a bit more details in the patch description part.
thanks,
Takashi

- r3: 0x20 (b7 is zeroed just before playback (except IEC61937) and set
just after it to 0xa0, presumably it disables/mutes some analog
parts when there is no audio.)
