OK, just picked up a brand new XP machine yesterday, love it so far. Unfortunately the sound quality through the headphones or speakers is horrible. Not a small speaker problem (I realize what to expect). What I'm getting is horrible reverb/echo. I assumed right off the bat that it was probably a setting (sound card set to "concert hall" or some other simulated setting) but I've looked everywhere and can't find anything for such a setting. I've checked the advanced driver controls to no avail. Is this a common problem? I'm not expecting head-fi quality SQ but do expect standard old cheap mp3 player quality stereo. All I'm getting is this muffled cavern like echo sound. What to do?
