I have a computer abd my sound is all mufles and cracky. It sounds as if my speakers are blowed butthey aren't as i ahve tried another set and its the same. Actually I have went into my volume settings and changed some stuff and now I have very low sound that is clear but it won't let me turn it up without gettin the sme problem. I have fooled ar ouns with my settings a bit but nothing will change. My volume settings is on very first strike and my s peakers are as high as they can go thats the only way that i can get anything fr om them . The second I turn anything up its all crackled and everything. My soundboard is a VIA AC'97. Can anyone help me get this fixed?
