Unfortunate to hear that Ifi does not provide better customer support. Have you tried using the exclusive mode with your Zen Stream DAC combo? My Zen Stream app is set to USB out/Chord DAC. Then moment I switch from AIO to Roon exclusive mode, it immediately switches to SPDIF. I read somewhere that the exclusive mode does not work if the Zen Stream is in bridge mode. I don’t quite understand how all that works. I have looked at several threads on this topic, but no real solution that I can find to keep the Zen Stream in USB out.
iFi Zen Stream (No USB output in Roon exclusive mode)
I recently purchased an iFi Zen Steam. The Zen Stream is connected via Audioquest Diamond USB to a Chord Cutest DAC. I was able to set the output to USB (Chord Cutest), but as soon as I turn on the Roon Exclusive mode it automatically switches to the default SPDIF. The GUI can not be accessed while in exclusive mode so I can change to usb output or used the Roon exclusive mode that is suppose to enhance sounds quality. What am I doing wrong? I also tried to change the output in Roon to USB, but it won’t let me. Thank you in advance for any help! Thank you!
