Hi I have a Dell inspiration 530 and untill now it has run well, It is loaded with XP professional, however during the last couple of days the sound system has changed the settings, how I do not KNOW I down loaded a track from the net and now if I try to play any music now the Band / Orchestra or backing SINGERS sound fine, the main VOCAL seems to be SEVERAL hundered yards away and is barly audible on a lot of tracks loaded on the hard drive, and played through microsoft windows media player 11. I have been into the settings  and tried to alter the realtec HD sound effect manager but nothing seems to have any effect. I cannot revert or reset  the system to the settings that were fine a week ago.

Is there a reset I can activate or am I missing the plot here, why can't I adjust the system so it sounds normal, would apreciate any help or suggestions Did you try to reinstall sound driver?CHEERS for that Broni,  took a little time as my expertise is minimal but got there in the end, and everything working fine.
So thank you again a brilliant help
