help with sound

i have a asus p4c800 deluxe mobo. the sound worked fine until i installed musicmatch. when i put a cd in to play, musicmatch starts but there is no sound coming out of my speakers. if tried uninstalling it but when i tried to play a cd i gave me an error message that said that mmatch.exe couldnt be found. hot do i fix this? how do I change the default player to not use musicmatch? is it the mobo? thx for any help

to change the default player just right click on a music file-->open with-->Choose Program--> Pick your program and make sure that the box "always use this program" is checked

Under device manager>cd drive>properties>properties tab>, make sure you have "Enable digital CD audio for this CD-ROM device" checked for all your cd drives so you don't need to attach an audio cable to your motherboard/sound card from your drives for audio CD's.
