Okay so I haven't had this problem within 3 years which is how long I'm using Camtasia now. I'm using Camtasia 8 but I'm planning to get the update soon. Okay so here's my problem: I usually record Let's Plays with Fraps and paste the files in Camtasia afterwards to edit them. The sound has always been fine. By fine I mean the audio of the Let's Play and my voice didn't have a static sound. It sounds muffled now. But here's the thing: The audio sounds perfect BEFORE pasting the file into Camtasia. So the videoclip itself is perfectly fine but as soon as I put it in Camtasia the sound is completely different and sounds kinda static-like and odd. especially at 's' sounds or other loud noises. It happened after I switched from a notebook to a PC so maybe that's what caused it? I really don't know what to do anymore. Hope someone has a solution:) Btw sorry about any mistakes since english isn't my first language.
