I've spent a lot of time researching this on the forum and other sites. MC and the Chord Mojo are working for me this morning
although I can't explain why or what has changed. Nevertheless, I'm pleased that it is working.
I've been looking at and trying to understand Zones and Zone Switch. As I understand it, I can set Audio Device for the: Mojo (Audio Device: "front:CARD=Mojo,DEV=0 [ALSA] Mojo, USB Audio, Front Speakers" (I was previously advised that is the preferred setting for the Mojo) and a separate configuration for the Id without the Mojo (Audio Device: default:CARD=PCH [ALSA] HDA Intel PCH, ALC283 Analog, Default Audio Device".
When I go to Zone, I can add a new zone, which I did for the "Mojo" and the "Player" with each linked to Audio Device - Device Settings. I then went into ZoneSwitch, where I added a zone for the Chord Mojo and another for the Player with a Display Name for the Chord Mojo and the Player and each linked to the zone selected from "Play in this zone". I think I on the right track. Can someone confirm that?
I also want to explore more about DSP. That will be next. Thanks.
