No sound in-game?

[pufig]

So after being unable to play for a variety of issues with the new version, I'm finally able to access the MS.

Now however, I am unable to get any sound at all when I enter a server. Sound is fine when I'm playing against bots etc, however no sound in multiplayer.

I had a quick search of the forum and it didn't come up with anything similar.

Cheers.

change ur sound quality to middle in system menu
