I don't have the option inside realtek hd manager to disable it.. Also what is weird under my speaker conf. where is says stereo its grayed out and I cant adjust it.....
It almost sounds like the driver wasn't installed correctly and some of your options are grayed out or not available. If you go into the device manager, do you have any devices with a yellow exclamation point next to it? Also, if you list the version of the HD manager you have, I'll check it against mine at home later.
Also, have you tried reinstalling it? If I remember correctly, if you run the installer with the driver/manager already installed, it actually uninstalls the driver/manager, forcing you to re-run the installer a second time.
