It would be very interesting (and may attract audiophile users) to have a flexible multichannel audio routing.

Here's some links that may inspire:

Ok, just discovered these opensource/cross-platform DSPs by Achim Touran (a Kodi/AudioDSP dev): http://achimturan.github.io/

Something along the lines of Equalizer APO(E-APO) would be great... and allow me to use my custom Stereo->5.1/7.1 Upmix, and also use my headphones as rear/side channels :-D

For example, with E-APO, I can swap front and back channels with a simple text file that read:

Copy: Temp_L=L Temp_R=R Temp_SL=SL Temp_SR=SR
Copy: L=Temp_SL R=Temp_SR SL=Temp_L SR=Temp_R

Or using similar commands create a simple, yet effective, "Stereo to 5.1/7.1 Upmix". Reduced to its bare minimum, it looks like this:

  Copy: MID=L+R

  Copy: SL=L+-1.*R
  Copy: SR=R+-1.*L
  Copy: C=0.5*MID

  # Fake some cheap LFE signal here:
  Copy: LFE=MID
  Channel: LFE
  Filter: ON LP Fc 600 Hz
  Filter: ON LS Fc 300 Hz Gain 1.5 dB
