Hmmm, interesting task. However, I don't think that this is possible 
currently. Output devices are currently designed to handle one audio 
channel, not multiple at the same time. Mixing them to one would require 
decompressing and re-compressing them and would probably introduce 
timing issues.

There may be a quirked solution like playing back the second channel 
externally, like connecting to it using mplayer+streamdev, however thats 
not very comfortable.

The best solution is probably a dedicated plugin that connects to live 
view and plays the secondary audio track in parallel. However I don't 
think that such a plugin exists currently.
