For now we are just planning to use two Y-connections for the SUB-L and
SUB-R and give one output to amplifier and the other (stereo 2 track) to
the sound card(on board, and still planning to get a real one). This
seems to be the simplest configuration (as Roberto suggested) and would
be good enough for the speeches. For the musical parts we plan to use
the mixer for the time being.

Hmm....wave, that means another added task of wave -> ogg conversion.

Ardour is great. But I think we might go with Audacity as sometimes none
of the tech-savvy people are there and we want others to be able to
learn application usage easily.

Yes, we are looking into a new audio card and will probably use the
onboard one till get the new one.
Thanks for all the tips Roberto, Raffaele, and Douglas.
