In CC2015 – which is the only thing I have loaded at the moment, but does work for some earlier versions:
In New sequence dialogue, when choosing a preset, select the ‘tracks’ tab.
You want to master to ‘multichannel’ and choose ‘4’ channels
Make A1-A4 ‘mono’ set A1&2 to output to A1&A2 and A3&A4 to output to A3&A4. Pan odds to left and evens to right.
(optionally save a preset)
Click OK – you now have a 4 discrete track timeline where, for example, anything on A3 will output to A3.
Now select a source clip (assuming 4 track source). Right click and ‘modify | audio channels’
Choose ‘mono’ and enter ‘4’ in number of audio clips
(optionally save a custom preset)
Click OK
Drag/Edit clip into timeline – voilà ! the languages will play out of different speakers (and you likely won’t hear A3 and A4 unless you select ‘monitor all channels’, above the master fader, in the audio track mixer).
If you got this far, and it works, then you will still need to modify your export settings to be 4 channel – it all defaults to stereo
