Win XP Pro + SP3 + updates WMP 11.0.5721.5268 1 admin acct, several limited user accts I have a purchased audio CD that produces no volume in a user acct but plays correctly (with volume) in the admin acct. In the user acct I have checked all the volume controls, have run MS's troubleshooter utility, etc. No control that I can find is muted. In this user acct I can hear system alerts. Furthermore, with IE8 I can go to websites and play and hear videos. What can be blocking volume from a purchased audio CD that plays correctly in the admin acct?
