ok with my sound card it is an sound blaster aduigy gamer, this just strated to happen tonight and it is really pissing me off a lot. i just reformatted my pc about 48hours ago and it was all fine until not, every mp3 i play sounds like crap, when the song hits a certian tone it makes a sound like someone hitting a cardboard box. or something like that, i first thought i blew a speaker but they are all good and everything wounds fine when i plug it into my laptop and cd player..i have uninstalled and re installed the drivers, software, and updates many times but now i am out of ideas. anyone encounter this problem before or herd of it and know how to fix it??
