1. If I use source number of channels, two-channel sources play as expected but multi-channel records will not. When I try playing a multi-channel recording with source number of channels engaged, JRiver demands I change to a two-channel zone configuration and offers to do it for me if I click yes but never does it send out a 5.1 package.

That sounds like your issue is that you haven't got 5.1 playback working at all via Media Center, not that anything else is the problem.
You need to get that working first. I'd start by checking that your device is configured to the maximum number of channels that it supports in Windows' Sound Settings. (right-click the speaker in the system tray and select playback devices)

ie. 3.0/4.0/4.1/5.0/etc would all become 5.1, and 6.0 would become 6.1 or 7.1 (6.1 is sometimes badly supported as well, and very few people actually have a rear/surround center).
Of course this might still prevent an external processor to process a 3.0 signal as it was 3.0, instead it would see a 5.1 signal, but most processors would likely not be able to do anything with 3.0 or 4.0 anyway, but only stereo.

If I understand this correctly, this would be a new option in addition to "Source Number of Channels" which would be something like "Source Number of Channels (common formats only)" which would basically see Media Center change the output between 2.0, 5.1, and 7.1 where appropriate?
That could work well without making the configuration overly complicated.
Thinking about the problem some more though, do most people actually want "Source Channels" or are they really only looking for stereo sources to be output as 2.0 and multichannel sources to match their speaker layout?
The easier solution for this may be a checkbox below the mixing options which is "Output a 2.0 signal for stereo sources" which would then let you specify whether the system is 5.1, 7.1, or anything else, in the "Channels" selection.
EDIT: I see that you added a similar comment to your post. That's probably what people are actually asking for.

Aren't these matrixed formats which present themselves as a 2 channel signal?

That is incorrect. As I have stated on several occasions throughout this thread:
1. Multi-channel playback from JRiver works PERFECTLY on my system but ONLY if I first select a zone in JRiver defined with 5.1 channels out. If I try to play a multi-channel recording using a zone defined with "source number of channels," JRiver refuses to do it and demands I (or it) switch to a two-channel zone.
2. Two-channel playback from JRiver works PERFECTLY in my system but ONLY if I first select a two-channel output zone either configured with two channels or "source number of channels.
3. Playing two-channel recordings via a 5.1 zone setting does work but is unacceptable because JRiver still outputs a 5.1 package with three channels containing no data. That limits me to stereo playback because my surround processor still sees a 5.1 package and therefore will not engage two-channel DSP processing. Regardless of the brand, this is how all DSP surround processors function.
4. Ergo, JRiver works PERFECTLY in my system. The problem is that JRiver cannot play two- and multi-channel recordings consecutively without manual intervention to change the output zone. "Source number of channels" does not function as its title implies it should.
I just want JRiver to keep playing music sans manual intervention with the desired results and keep playing until I tell it to stop whether the recordings are all two-channel, all multi-channel, or a mixture of the two. That is, after all, the working definition of a playlist.
My suggestion is that if the output zone is defined as multi-channel and the source is only two channels, JRiver should dynamically switch the output to two channels. This could either be by default as Roon has chosen to do or by an optional setting. I would be happy to beta test this.

So if you disable Zone Switch, and change that zone from "5.1 channels" to "Source Number of Channels" in DSP Studio without making any other changes you are no longer able to play 5.1 files in it?
tbng:
That is correct. Source number of channels has never worked with multi-channel sources.

Before we go further, please clarify what you mean by "disable zone switch."
