Who Me Too'd this topic

I have sound everywhere EXCEPT multiplayer.  I can hear everything up until I join the game, even the loading screen sounds.  But once I join the game, POOF no sound, nothing.  I have tried all the settings, and my graphics and sound card drivers are up to date.  I do not see a trouble shoot for this yet, please help!  Kinda hard to have any good game play in Multiplayer if I can't hear anything.  thank you.
