Hi all,

Am doing a multi user audio chat application, I would like to know what are the cause for echo in that, i have echoSuppression set to true, and also i would like to know how to use the netstream.play() method.

I have some piece of code like this,

First am playing a livestream like this,

NS.play(“livestream1”);

Here comes my question,

Next when i want to play a second stream “livestream2” (after closing the first stream “livestream1”) can i use the NS.play(“livestream2”) directly or i should give a NS.stop() and then start playing the second live stream.

Please advice me on this.

Thanks,  
Saddu.
