VB and my Sounds

[Foaly]

Hey,

Since one day I always had problems with my sounds. I've got a 5.1 system and the balances have been surprising. Now I hoped to solve all problems re-installing the os and they wer solved. but now, 2 days later they are back. i'm not sure, but I think it depends on the installed VB. Is there anybody who has the same problems? or somebody can tell me how to solve?

thanks
