Sound dropping out

[Slybo]

It has happened a few times now where all the sound in the game will cut out. I have to quit and relaunch the game to get it back.
Is this a known issue?

Win7 64bit
AMD 4core 2.50ghz
6gb ram
Logitch G35 Headset

I suspect its an issue with the drivers for the headset.

Intel Core 2 Duo T5800

NVIDIA GeForce 9650M GT

Sound is back after the game is restarted only happend in episode 3,4 and 5.
