Hi, My toneport ux2 have worken briliantly until now. When I play guitar using gearbox, it works for like 10-20 minutes. But then all of a sudden a noise spits out of the speaker and your ears just starts bleedeing. The sound continues and you have to restart the whole computer in order for it to disapear. I Cant even change soundcard or disabled it. It still sticks and it sounds like hell. I have the latest driver installed using line6. What can be the problem?
