No Sound and file is not supported


Hello, amazing program that actually works great !
However there are two major issues iv'e experienced:

1) No sound when using the desktop stream to TV (it says on the tv that the sound is not supported) - tried to change to another audio codec but there are only two and none of them is streaming sound to my TV.
2) Tried to watch TWITCH (www.twitch.tv) but it says "file format does not supported".

Thanks for listening
