Hi @Geoff and @Geoff_Coupe: 
I’m going to back up and ask a more basic question to start with since this started with not being able to hear anything although something appears to be playing. I see in the Meridian setup that your volume limits are set to zero min and zero max. You’ve given volume control to the device, but the Volume limits override your selections once those limits are reached. In other words, it looks like you’ve told your Meridian speakers to never exceed zero volume. Try going back into your device setup and move that max volume to a higher number - I’d start with 50 or 100
Once we can make progress here, I may split this topic so we can address the library and files separately. Don’t want to do that prematurely though.
