Hello All,
Newbie here. Have been using Logitech Media Server for past year or so on an old PC but am planning to try out Volumio as it fits my need perfectly.
I had purchased relatively inexpensive USB DACs and they are connected to the PC via 8 port USB hub.
DAC Name: ELE EL-D01 MINI HIFI USB PCM2704 DAC
amazon.com/EL-D01-MINI-PCM27 … ds=USB+DAC
I just purchased Raspberri Pi over the weekend and installed Volumio on it (the latest Beta Build for Pi). I attached the above USB DAC but I am receiving no sound 
I then tried another inexpensive USB DAC that was lying around in my spares, its the little USB - stereo adapters
HDE 7.1 Channel USB External Sound Card Audio Adapter
amazon.com/gp/product/B0027E … UTF8&psc=1
Even this one does not work . Basically I have no sound on either one of them. I have tried with or without the USB hub but no change.
Both of these USB DAC work fine on the PC, so it must be a driver issue on Volumio or something.
Any suggestions on how to make them work would be really appreciated.
Thanks for all your help.
