The Rpi needs to see your “asynchronous USB receiver board” as a “USB audio class 2” device. If your board happens to be based on an XMOS chip, for example, then it should be recognised.

HOW TO?

1. Connect USB cable between Rpi and DAC. ( Rpi should auto detect your USB DAC and load the required sound module)

2. Select USB audio device for output – MENU > MPD > Audio Output - Save & Apply
Thanks, I'll have a go but using Rune Audio I don't see a USB DAC option under audio output, though I didn't see a Digi+ option either till I edited config.txt so I'll have a look there.

The board is a bit of an odd one (Musiland) it works great with a PC laptop but they never got their act together on Mac (there was never a working driver).
