You mean, after installing the 4650, the soundmax does not work any longer? Then goto control panel / sound / playback devices and switch the standard device back from hdmi to your soundmax. That's it.

there are no devices in playback

Drivers installed (amd and soundmax)? Exclamation marks in device manager?
