Win98 sound loops

I have a Compaq Deskpro PII 233 with 98m RAM,creative RAGE 4, ESS1869 sound card, now it was working ok, a friend tried to install sound blaster drivers( for some reason yet to be confirmed LOL)
I have reinstalled the ESS drivers and updated them from ESS web site.But when any kind of sound is played through the WAVE section on the Vol Control all i get is the first note LOOPING around. when the WAVE is muted, i can hear from the mic. please Help me. Thanks in advance Iain
