Ok my problem is that.Normally i have sound in windows i can listen to music etc.But when i start tremulous my headphones start to make noise like trzhhzhzhzhrzhzhhzshzzh and even when i close tremulous the voice starts again when i want to listen to music etc and i need to restart computer.I never had this problem before it started like 2 weeks ago i had drivers problems but i downloaded new one and voice is working.But no sound in tremulous;/ just trzhzhzhzhz all time.My drivers are CMI9761_71( c-media ones)
