What was the exact question you asked them? Obviously a music stream won't go through the computer DAC (converted to analog) and then get re-digitized to go out on USB.FYI - Reached out to Qobuz tech support to ask... they said:
Thanks for contacting Qobuz support. I'm happy to help. You are absolutely correct. The volume slider controls the input to your DAC. The sound is not running through the Apple DAC if you have an external DAC selected.
The fundamental question is whether an external DAC can receive a bit perfect copy of the original Qobuz stream. I believe that it does, under the right conditons:
- Volume in the Qobuz app is set to 100%
- No other app (or the system) is sending audio to the external DAC at the same time. When more than one source sends audio to the external DAC simultaneously, MacOS will mix the sources together.
I do not believe that MacOS implements the concept of "exclusive mode" audio, where an app can gain exclusive access and block other apps.Edit: In Tidal, if you set the external DAC to exclusive mode, MacOS will not allow you to choose it for system output. Qobuz has not implemented this feature.
