CLOD Sound unstable

[ramstein]

The sound in CLOD was going up and down,, very unstable.. I was flying in the ATAG server, and while flying, the engine sounds in a Spitfire were going up and down,, low and high.. I could not hear people talking on TeamSpeak3 because of the erratic engine sounds.. I wondered if there is already a thread for this? is this the right forum? It seemed better before today, maybe it was just a bad day on the server... do thers have this problem too?

the top sound slider is now set about 1/2 the way, the next 2 sliders, at the bottom, are all the way to the left (off) I think they are voice and music, both off..)

Win7 x64
Duo2Core 3 ghz cpu
Nvidia P7n MSI motherboard (built in sound)
4 gb DDR4 ram
PNY GTX460 video card with 1 gb ddr5 ram and 256 bit
500 gb of hard drive space... (3 hard drives...) (Sata and IDE both)
Saitek X52 Pro and Saitek Pedals.

I use COD software on Steam.

Thanx..
