Sound stops working after map change

[El_Swine]

Win7 64 - Intel - Nvidia - Audigy 2 zx.. So its not sound card related as it seams we have all kinds here.

I've noticed it happens when map ends and you continue to fire just as the closes.
It will be silent after that.
I've also noticed that it seams the sound is going gradualy away.

Have a look around on the nett, it could be common UE3 engine error.

map switched from red october to spartanovka, there was a pop noise and then no sound.. seemed to happen to at least 3 or 4 others at the same time.. when i was exiting the game the menu selection sounds were also 'pops'...

So freaking annoying, and the sound is maybe one of the best parts of this game, it cuts out on me almost every map. Happening since one of the recent patches.
