This is new.
When I play JRiver on my Mac - I output via USB to an Oppo DAC and then analog out to RCA inputs on my Marantz.
I had no problem until today. When I played JRiver songs, there was no audio coming from my receiver regardless of music file format (DSD, mp3, etc). After checking everything I concluded the Oppo DAC failed.
Then I wanted to check something on the receiver menu system and I turned on the TV so I could view the receiver menus. About 2 or 3 minutes later, the JRiver audio came on !!!!
I turned the TV off and the audio went off. TV back on --> Audio back on !!!
What in the world does the TV have to do with the Audio? I just have right and left RCA analog inputs from the DAC.....and no HDMI need whatsoever.
[ I realize this may be a Marantz issue, but I thought I'd throw it out here]
UPDATE: It occurred to me it may be a CEC control issue with the TV HDMI....so I checked the TV and control was ON. I turned control off and the receiver power stayed on but the audio went OFF [ARGH] --- I turned it back on [audio came on again] and checked CEC in the receiver. It was off.
UPDATE #2 - Solved. I pulled the plug on the receiver and waited a minute.......plugged it in and all is well again.
