Request change in handling of multi-channel
Fitzcaraldo215:
Meridians are rare birds. But, even there, I think you are way off the mark of what is happening. A Meridian just absolutely does not stop play by JRiver in order to do DSP.
tbng:
The Meridian HD621 is an HDMI switch with multiple inputs and one digital output. It does no DSP but transmits the digital signal via a single set of non-HDMI cables to the 861V8 (or other Meridian processor) where the DSP audio processing is accomplished. Based on how it acts with other sources, it sees any number of channels passed to it. I believe blaming the HD621 for any of this is going down the wrong path.
RoderickGI:
Sorry guys, I Copy/Pasted the wrong Meridian component when I wrote that, and I wrote it in a hurry. I have updated my post above. Re-read it and see what you think.
This is nothing to do with blame. It is about understanding what is happening, and hence resolving your issue.
My understanding, and what Hendrik has written above, is that MC needs to know the capability of the target audio device. If it is asked to send 5.1 channel audio to a device that it believes only has stereo capability, then MC will offer to send it as stereo, which is exactly what you have reported as the observed behaviour.

Configured with "source number of channels," JRiver cannot and will not playback a multi-channel source but demand that the user change to a two-channel output configuration to continue. The name implies that it functions as an automatic channel selection setting, but it does not.

MC won't switch to the source 5.1 channels when it believes it is playing to a stereo device.
In fact, having the Meridian HD621 between the MC PC and the Meridian 861V8 may have an influence on MC's capability to determine what the target audio device is capable of. Because tbng, you did say;

"HD621" refers to a Meridian HD621 HDMI interface that acts as the DAC in this case, although it sends the signal still in digital format to a Meridian 861V8 where the actual D-to-A conversion is accomplished.

So MC doesn't see the Meridian 861V8 as the output device it is playing to, but in fact, sees the Meridian HD621 as the target device. HDMI connections are fickle things, and adding in an HDMI switch could well be confusing MC.
Because it is the Meridian 861V8 processor that must communicate its capabilities when the source number of channels changes, and it must detect a stereo signal and engage DSP processing.
--- Quote from: tbng on February 08, 2018, 07:59:12 am ---I do not want to listen to two-channel recordings merely in stereo but want to engage DSP processing to create virtual surround. To do that, the processor must see a two-channel input. If the processor sees a 5.1 input, even if three of the channels contain zero data, it will assume discrete multi-channel input and not engage applicable DSP processing.

Is the Meridian 861V8 communicating its capabilities correctly to MC via the Meridian HD621 when the source number of channels changes?

You should remove it and connect to your AVR directly. Process of elimination.
BillT:
The 861 doesn't have HDMI inputs so can't be directly connected. That's what the HD621 is for.
