Hello,

I have a little problem. Probably trivial.
I use this incredible box in many ways.
Sometimes I wish to listen CD via optical out, using ADI as a DAC.
When the ADI is in USB mode I turn on the CD transport and I can see the incoming signal on the ADI screen, but no sound come to the output (monitors).
Even if I try to listen to a file in the Mac, the ADI is mute. If I turn off the CD transport ADI unmute.
When the Mac is off and ADI go automatically in preamp mode all is working fine, but without the computer I lost the acoustic correction of the Genelec GLM software.
How can I switch manually between modes on the ADI while is connected via USB?

Thanks in advance and greetings from Italy
