I have a problem with getting guitar rig 5 to work. My system specs are as follows Intel Dual Core e2400 1 GB RAM Creative Sound Blaster 5.1 VX Cort X-2 (Venom Skulls Edition) I first had an onboard sound card, I tried guitar rig on it, it didn't work at all. My friend had a cheap external sound card and he also had guitar rig and it worked for him, I figured my onboard sound card was the problem. So I bough a Creative Sound Blaster 5.1 VX and installed it into my computer. As my card was expensive, I expected better results than my friend. My friend doesn't have any additional equipment, he just plugs in one end of the guitar cable into the soundcard's mic using a connector, which I also have. He gets pretty good results with no latency or disturbance. I tried the same thing, guitar rig did produce an output sound, I was ecstatic, but then I changed the preset to a metal tone (A tone with distortion on) and every time I pluck a string, there's a sharp screeching noise that never goes away until I restart my computer. It seems to work fine with one of the clean tones. I tried an external USB sound card and it worked worse, it produced a screeching noise as soon as I started Guitar Rig. I was wondering if anyone here could help me with this, Is there a sound card that you tried that works with Guitar Rig, Do I need to buy any additional equipment. I've seen videos of Behringer Guitar Link working with guitar hero, it is expensive, I don't want to buy it only to find out it doesn't work. So, any sound card that you've tried that works?
