I have been using the Windows 7 64 bit release candidate since it came out and have not had really any big problems until today. It seems as though I can't open the window that lets me set the default playback device. When I go to Control Panel > Hardware and Sound > Sound > Manage audio devices, nothing happens. Nothing also happens when I right click on my speaker icon in the system tray and select "Playback devices"
I tried uninstalling my sound drivers and then restarting but that didn't seem to help.
Any thoughts?
