for dal or anyone with madden 2002

[kidace]

i have my copy of madden from friend but when game starts just toward the end of video the sound is messed up i also copied from other disk and it happens also during game play every now and then it will sound garbled but it only last a sec or so is this the case with all of them or i used the cdrwin method to copy not the clone cd if i did one on one copy will it work without me having to patch maybe then it might work better .
pls ans if anyone can.
