how to deal with multi audio tracks ?

[toto]

Thanks for reply.

But I really need some base element/functions to do with that. 

I tried to unlink one track source from adder and then release the
request pad. it does works. this track was removed, while the other
tracks play normally. But now i got another problem: i don't know how to
adder it to adder dynamically again...get request pad and link again
seems not work.

Is there any clues?
