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.


Cheers,
