I am operating Volumio on a CuBox i4 Pro with an ODAC as Sound Device. Everything is working wonderful.
A few days ago, I ordered the new ODAC Rev B and that DAC is giving me a poor performance.
The output level is only one third of the old ODAC. The noisefloor therefore is hearable. Audio mixer is disabled.
The producer JDS Labs says in his Tech Specs that the audio level should be a little higher than the old ODAC was.
Also the new ODAC Rev B needs to be driven by a USB HUB, the old one could be connected directly to the CuBox.
Under Windows everything looks fine, the new ODAC performs as good as the new one.
Has anyone an idea?
