I have a Windows XP and my sound quality is bad. I never remember it being this bad and I don't know how to FIX it.
I use iTunes to play my music, and surround sound speakers. The speakers are Durabrand model HT-3915.
Everything, no matter how quiet I TURN the controls on the speakers, my computer, and iTunes, it's fuzzy.
Edit: My computer is custom built... that's all I know.are you using sound card?have you ever update your windows?have you try the speakers ANYWHERE just to make sure the speakers alright?
if you using sound card,update the driver.If your computer is custom built what's your current sound card , and is your on-board sound card disabled in bios that can actually cause interference , find your current sound card by right clicking my computer going into computer management , and going into device manger there you will notice a few things , you what to make sure you toggle down to sound .... once there find out your current sound card , once you have pin pointed out yours be sure there isn't ANOTHER sound card enabled , if there is disable it ...... or post back with what you have SEEN and i will tell you if it is or isn't...

Tony Could it be the quality of the music. It should be pritty high to use surround sound speakers
