Pioneer DJM 900 as DAC?

Apologies, perhaps @gkkpch can make sense of it... My only thought is that a Pi Zero W might struggle to run Volumio and feed a hi-res DAC, but that's just a passing thought...

Hi Chris, i would use a pi b3+ but just had a zero around and thought it would be enough for the testing..

@felixheller,
looks like your Pioneer is being recognized.
Now it would be interesting to see the output of "aplay -l".
That should should the device as an usb audio card.

Hi gkkpch

As far as I know it has at least four ins and four outs so maybe this helps?
