sry sry i found my solution! Ive got the soundmax onboard(?) soundcard on my chipset/motherboard. Well i checked it on the internet and after a half hour search on the pr forum (:p) i found a topic with a few guys having the same problem, but with different solutions. Some said you had to download a previous driver dating back to 2004, but since i didnt reallty feel like doing that i searched a little further and there someone suggested putting all your soundsettings in -> configuration(control pannel?)->sound and applications(?) and putting all settings/speech/audio/speakers. On basic. Well i didnt really think it would work.. but it did:o so my voip is working again.
