No sound from media player or Real player

[Mizab]

I am having problems with not getting any sound from either of these and most games I play don't get sound either only game I get sound for is the pinball for windows.  Another place I can get sound is when I use my vinyl audio control panel when I got to test the speakers they work. I have tried to upgrade my media player and download the newest drivers for my audio.
The audio I think I am using is called Envy24 family audio controller WMD. Also I have another one called vinyl AC97 codec combo driver WMD.
I am running windows XP um not sure what other info is needed if I missed anything please tell me and I will post it right away also thanks for any help can get.

Delete all audio items in Device Manager and restart the machine. What happens now?

[Mizab]

um not sure what you mean like disable everything with sound in device manager. I don't know how to delete anything there. I disabled them all and then nothing at all works no sound from pinball or anything at all.
