I've successfully been using an rpi2 with an Audiophonics v.2.1 dac for a while now no problem.
Just got a linear psu from eBay to power the dac and pi, but it doesn't seem to be powering up with it.
My understanding is that this dac takes the power and also feeds it to the pi.
I've tested the psu and it works fine.

Is there anything I need to do to the dac?
