Congrats on the cool project! the interface looks great.
I'm having a play with RuneAudio on a RaspberryPi. I noted that v.1 specifically did not include support for the built in audio on the pi.
However, the description for v.2 says:
"Added analog output on Raspberry Pi (although still buggy)"
I've managed to setup runeaudio and it's providing access to my media but so far I have not been able to get it to play anything.
Right now, I'm just testing all this so did not want to invest too much in a DAC before I knew that it would all work. I tried to by an iqaudio but they seem to be out of stock.
Is there a way to get analog output working? Should I be testing with another low cost DAC instead? Can you recommend one that works well?
