I've been poking around the source for RasPlex and learning about how the universal transcoder requests happen, but I'm still a bit mystified on how to get the universal transcoder to spit out 5.1 audio. The debug log shows the ffmpeg command with "-ac 2" every time, and I don't know how to get it to do anything else.
I've tried adding parameters to the request like "&audioChannels=6". I've poked around at the client profile we were supposed to place on the server, but I don't even know if it's being used, and I certainly don't know how to specify a transcode target with 6 channels.
Is this something you guys know how to do, or should I spend more time to track it down? If you do know what to do, please share as I'm quite curious at this stage. :)
So I don't know much about the transcoder, and also not about plex. But it seems to me that everytime surround issues pop up nobody responds. It's just like it's a big mystery or maybe the devs don't use surround at all. It's the same over at xbmc. Kind of sad to be honest.
Sorry didn't wanna hijack your tread just an observation.
I too is very curious about how the players and the hardware actually handles surround in general.

One, the ability of the Pi to decode AAC5.1 into Multichannel (LPCM) and send it to the receiver/TV. That works fine in RaspBMC but according to that other thread you found, it's a relatively recent fix, and it may take time to filter through to RasPlex.
Two, an option to request that the server transcode AAC5.1 into Dolby Digital (AC3), so that the Pi can pass it through to the receiver/TV. That's the part that I was poking around in the source to see if I could make happen, and I still can't figure out how. It would actually help me solve a new problem - I bought a Vizio 5.1 soundbar, which works great with AC3 passthrough, but it can't do Multichannel. So even RaspBMC is insufficient for this soundbar.
I would very much like to see more options to select exactly what I want to come out of my pi, as the best thing for me would be multichannel 5.1 (LPCM). That is what I think happens when you deselect the DTS/DD capable receiver options in settings, but still has the audio output channels set to 5.1.
Unfortunately that doesn't work on my rasplex right now.... (see other thread)
