I have a DAC with a USB receiver board (Musiland 01) this works well with PC but they never quite cracked a Mac driver.
I have the RPi 2B working very well with Rune Audio and the HifiBerry Digi+ board but am wondering if USB output is possible? I can't see how to activate it, I edited config.txt (about the limit of my technical skill!) by removing the hash on the line for the Digi+, to enable I2S output. But I can't see how to enable USB - currently my only output options are Digi+, RPi Analogout and RPi HDMI out - no USB option. I'd like at least to give this a try. Any ideas?
