Description of issue
Marantz connection has always worked since I bought Roon last year, stopped working around 2 weeks ago.
Problem: When selecting system output to Marantz-AVR (Intel®) Display Audio), Roon scrolls quickly through all tracks of an album or playlist and stops with message ‘Nothing playing’. If Speakers/Headphone (Realtek High Definition Audio) is selected it plays Roon plays perfectly through the laptop speakers. Plugging a HDMI cable directly into Samsung F8500 plasma thus bypassing AVR plays perfectly from Roon.
Roon plays perfectly through CP800 (which is default device)
I have checked that both the Realtek and Marantz drivers are at latest update. Done the Marantz test in Windows settings (7.1), plays test tune perfectly to all speakers.
JRiver and iTunes plays prefectly through the Marantz - single and same HDMI connection.
Resetting PC, removing Marantz power cable and reconnecting, running Roon as only app open in Windows makes no difference.
Disabled and re-enabled the system output in Roon Audio settings - no difference
Swopped HDMI cable between laptop and AVR, used different HDMI inputs on AVR, checked every possible setting in the AVR (I know this AVR very well having owned it for years) made no difference
Very frustrating! There are nothing that was changed (Roon or Windows software) or settings between working one day and not working the next.
Please assist. I have even considered uninstalling Roon and reinstalling but really not wanting to do that!
