I managed to install my both DAC (aim Ultimate USB audio) on my RPI with max2play.
With this configuration I can have 2 virtual squeezebox on the same RPI and with two different sound cards.
But I have two minor problems:
– The sound level is different between the two sound cards… why???
– With Max2play, I can have a Airplay access but only one… Is it possible to have two Airplay access (one by sound card)?
