if you close a net stream do u have to make creat a new stream in order for it to play again?

i have multiple flvs that can play on the 1 page. flash only has 8 audio channels so once you get past the 8th clip - the rest play with no sound.

i think to close the netStream and free it up for others to use is the best way forward but if there is another, better suggestion id greatly appreciate it.

cheers people
