Hi. I have a very rare audio problem. The sound card might be glitched out or something. But it doesn't sound very clear. It sounds like the volume level is at 10 but I have everything maxed out. I have it at 100 and in-program volume maxed as well and it sounds like the volume level is very low and I sometimes have trouble hearing what is going on in my games. I can only hear the big stuff. It also sounds like everything is distorted. It doesn't sound clear neither. It overall just sounds like crap. I need to use some sort of disk cleaner or something to clean out the glitches or something? Anyways, the audio card I have is "IDT High Definition Audio Codec". I have couple others listed in my device manager and not sure why or what they are. They are "Bluetooth Hands Free Audio", "Bluetooth Stereo Audio", and "High Definition Audio Device". Not sure if the sound card is actually "High Definition Audio Device" or "IDT High Definition Audio Codec" but I think it's the latter. I think it's just glitched out sound card and I need some program that will clean out the glitches and/or restore it to it's normal/fresh state. Btw, I am not the one who bought or customized this computer. And its.... Dell. Lol I hate Dell. My step mom picked the parts and bought it. I'm using Windows Vista and it's Dell XPS 420.
