Hello,
I have an older version of JRiver. But guess all same. I use JRiver only for Music from computer to surround. I got a Denon Avr 1400.
With a USB Dac, no issues. But that sounds too thin for me. But on HDMI, I have issues.
First, JRiver will only see the Denon receiver, when projector is on (not use TV). Bit annoying to put it on every time, but so be it. When putting projector off, after playing movie, have to restart the music again. But if I not configure the computer, by leaving the screen on all the time, it will stop the music every time the screensaver gets on. I tried a lot of other things. Use Audio only in JRiver, extend the screens, computer and Denon/projector. Put the computer screen off manually, but every time the music will stop playing, if I not let the computer screen on.
Feedback welcome....
