It has been a bit of battle since purchasing the Trinnov, mostly thanks to HDMI, i.e., Hellishly Demented Moronic Interface.

Here is a problem that shows up on the Trinnov display that may or may not be JRiver's issue.  Whenever I play a multi-channel recording via JRiver (via HDMI), the Trinnov shows the correct sampling rate.  But whenever I play a two-channel recording, the Trinnov only shows a sampling rate of 48kHz regardless of the source sampling rate.  (Makes no sense that the channel count would be causative.)  I would blame the Trinnov except that it always correctly shows the sampling rate of CDs played on my OPPO regardless of the channel number.  I have JRiver's DSP options set to no sampling rate changes through 96kHz and higher rates reduced to 88.2 or 96kHz as applicable (until I upgrade my external DAC) in both the two-channel and multi-channel zones I've defined.  Is JRiver functioning properly in this respect?  The Trinnov is implying it's not.

Apart from the above and as a warning to any of you JRiverites intent on buying a Trinnov:  Its room processor is superb, but it's a temperamental beast that refuses to live happily in a diverse world of 2.2 and 1.4 HDMI video devices.  Above all, do not believe Trinnov when they say they do not recommend making connections from both the 2.2 and 1.4 HDMI outputs simultaneously.  They should say that UNDER NO CIRCUMSTANCES should you EVER make both of those output connections simultaneously, or the Trinnov will CRASH, which was the source of the problem I reported here earlier.  HDMI on the device is passthrough, and the OS clearly cannot gracefully handle the errors those simultaneous connections cause.  JRiver only re-found the Trinnov device after I disconnected the 1.4 output and rebooted after a LO-O-ONG wait.

But JRiver is not a HW piece, maybe that's an issue with your motherboard?

I have no idea what an "HW piece" is.  Motherboard of the Trinnov??

What is the sound path in JRiver when you stream stereo content?

[tbng]

HDMI is the only sound path I have ever used from the Win7 music server to my surround processor, using two-channel and multi-channel zones in JRiver.

There is an icon in the main window's top right corner area, what do you see there (during stereo playback) ?

Per the info behind the gear icon, JRiver converts a 352.8 kHz .dsf file to 88.2 kHz (presumably PCM).  It seems that JRiver is outputting 88.2 kHz.

[Awesome Donkey]

To explain the 352.8 kHz to 88.2 kHz result, MC is converting DSD to PCM at 1/8th the sample rate of the 2.8 MHz DSD file. So the DSD 2.8 MHz-to-PCM conversion formula would look something like this;

2.8 MHz DSD > 352.8 kHz PCM

That said, I believe you mentioned above your DAC doesn't support sample rates above 96 kHz so since 352.8 kHz isn't available it's instead converting to 88.2 kHz. You're probably wondering why 88.2 kHz and not 96 kHz? It's because 88.2 kHz (along with the higher 176.4 kHz sample rate, etc.) is a multiple of 352.8 kHz. 88.2 kHz times four equals 352.8 kHz. Or if 176.4 kHz was supported, it'd be 176.4 kHz times two equals 352.8 kHz. So that's why you're seeing that result.

If you desire to have it output at 96 kHz instead, the workaround (at least until you get a new DAC which supports higher sample rates) is to set DSP Studio > Output Format and set 352,800 Hz to 96,000 Hz.

Now, if the Trinnov is still only displaying 48kHz it sounds like there's another conversion happening somewhere else in the chain (perhaps on the Trinnov itself?) and/or it only supports 48 kHz sample rates or something like that. In this case in regards to MC, it looks like it's doing what it should be doing correctly, as the Audio Path shows.

The Trinnov - as advertised - supports all sampling rates, passing them through unmodified.  It's just that the outboard DAC I use for the front channels is currently limited to 96kHz.  The question remains as to why two-channel recordings above 48kHz are being limited.  It does appear that JRiver is correctly outputing the sampling rate.
