Hello everyone... i have a problem, and i need your help please... , I have the Guitar port, I have bought it since 2006, but since I installed it on windows 8 it does not seem to co-operate with my sound card, for example when i watch a video on you tube, the sound suddenly stops and sometimes the video stops loading. If i turn off guitar port and register the sound card of my pc as my sound card all goes fine, I would like your help on thus matter please. I don't know what to do. Thank you
