I installed RuneAudio on a Raspberry 2. It's working really fine but a separate DAC is needed definitely. Since I also need a new, smaller amp (restricted space), an amp with integrated DAC would be nice. So I found the TEAC AI-101DA. I surely could use the toslink input with a HiFiBerry Digi+ or similar, but using the amp's USB port would be nicer, because no HiFiBerry is needed and both toslink inputs would be free for other sources. I couldn't find a definitive answer, does RuneAudio (or Linux in general) support the USB port of the AI-101DA?
