Recently my onboard sound (via ac97) started acting up it would play sound from the line in quite well..but if i opened up a media player and played music the sound was distorted,scratchy and sometimes slow.So i recently purchased an aopen aw850 deluxe sound card.Before installing it i reformatted my system (windows xp) and installed the card,everything worked great for a few days,but now the new aopen sound card is doing the same thing as my old onboard sound was doing...I cant figure out why i can play music through the line in which is hooked to my tv,and my stereo and it plays great but if i open up a media player the sound is terrible,slow and almost at times sounds robotic...i have tried to update drivers using windows update but when i do the line in stops working,and the sound doesnt change..i have tried everything i can think of from updating my motherboard (msi)(amd processor) to trying several different media players,and even disableing hardware acceleration but nothing works..i have my onboard sound disabled through bios like i should can anyone tell me what might be the problem???? please help!!!
