Hifiberry OS with USB DAC
Until my Hifiberry HATs arrive I wanted to try hifiberry OS with a USB DAC in Roon (I used a Dragonfly Black)
While everything seems ok in Roon - the endpoint is seen by Roon and I can play music on it there is no sound.
Is an external USB DAC not supported? Does hifiberry os only allow hifiberry HATs?
Or is there some configuration that I missed?
Thank you
