Ok well this has been a problem now for several years, i just kept putting it off. I always got around it, but now i am FED UP!!! I use an HP PC. Pavilion m7570n. Problem is that i record myself live on either my logitech cam, or like windows movie. However, when i do, i am getting a clicking sound, that is VERY ANNOYING. Some times low in volume, sometimes high. I think the harder i play, the louder it gets. Before this began, before i did any recording on pc, i went to guitar center and said this. What do i need to do recordings on my pc? They said this Saffire 14 (focusrite) So I bought it. hooked it up. Only hook up is firewall cable going to the back of tower, and the plug for outlet. Was this the right gear that i needed? Now i hook my guitar up to a Boss gt-6b, and into the front of the saffire. Is there a setting on the pc that is causing a disturbance? I am at my witts end, and need help. Alls i wanna do is record on logitech, or win movie. I would have gone out a long time ago to get imovie, but no money at moment. Please tell me it is a setting on my pc. very annoying clicking. ANd as far as i believe, all settings for audio are correct. Thank you for any help.
