I've been having an issue with playing back DTS-HD Master movies with JRiver since JR 25. I've tolerated it because I can restart my computer and then playback will work. I think I finally have s clue as to where the problem is, but am not sure where to go from here. When the problem in JRiver ocurrs, I get the error


Playback could not be started on the selected audio output.
The audio format may not be supported by your hardware. You can use DSP Studio to change the output to0 a compatible format.
Also make sure that your system has a valid sound playback device and that it is properly configured in playback options.

As I have discovered, the problem appears to be related to the NVIDIA High Definition Audio Driver. When the problem playing DTS-HD Master content appears, the marantz-AVR device under the Windows sound properties, Supported Formats only displays:
Dolby Digital Plus
Dolby TrueHD
Dolby Digital

When it all works after a reboot, the same Supported Formats dialog also displays:
DTS Audio
DTS-HD


The optimal solution is to never have those DTS formats disapear from the driver, but my guess is that there is nothing that I can do to prevent that. I wonder if someone knows a way that I can somehow reset that driver from the command line using automation to reread the supported formats.

The receiver may be having trouble switching.  Try using DSP Studio > Output Settings to force everything to the same output.

Pretty sure when using Bitsream, DSP Studio settings do NOT apply.

You could try various different nvidia driver versions, the latest is not always the best. If you are running multiple displays, remove them so that windows only sees one display device.

Aside from those, my guess would be the dr hdmi device and/or your hdmi cabling/length/multiple connections. Unfortunately the best test would be to bring the Tv, AVR, PC into the same room and connect them directly with three "premium certified" 6ft hdmi cables. No dr hdmi, no wall plates, no 33 ft cable, etc.
