Thanks.
However, I don't see in its schematic diagram DO – only Out 1, 2, 3, 4 which are VOUTR, VOUTL and 2 grounds. Or is the DO assigned to 1 of the I2S lines?

I've been unsuccessful at getting the Usb module to work with the Buffalo as I2S. If I connect it for I2S as suggested below, I never get any sound or LED lock. If I switch the connection to the 2 wire S/PDIF connection, it works well. Can you make any suggestions as to how to troubleshoot this?
thanks

There are two ways you can connect the USB module to the Buffalo: I2S or S/PDIF.
To use I2S, set the jumper on the USB module to I2S, the S/PDIF switch on the Buffalo to off (the side marked "1"), and switch 1 on the Buffalo to "-". Then make the following connections:
USB BCK -> Buffalo DCK
USB LRCK -> Buffalo D1
USB DO -> Buffalo D2
USB GND -> Buffalo G
To use S/PDIF, set the jumper on the USB module to SPDIF, the S/PDIF switch on the Buffalo to "On", and switch 1 on the Buffalo to "+". Then make the following connections:
USB DO -> Buffalo SPDIF
USB GND -> Buffalo G

is using the USB output as I2S inherently better mode than using the USB output as SPDIF? Will one be better than the other with regards to PC noise floor?

I guess my question is also the same as the one above, I cant seem to get the USB I2s to work, but the Spdif works well. Is there a benefit to getting the I2s to work? Or is the spdi/f just as good?
