OK so sound was definitely working fine a couple of hours beforehand. Did not install anything or change any settings, etc. I decided to launched a game, and realised there was no audio. I tried to bring up Volume Control from the system tray, and was greeted with the error "The audio device supported by this application is not detected. The application will exit." Didn't sound good. BTW, this was while using my Creative Sound Blaster Audigy SE card.
The next thing I tried to do was to connect speakers to the integrated card and see if that worked (Soundmax audio device on P5B Deluxe). No luck. I also noticed that in Sound and Audio Devices under the Control Panel, it said "No Audio Devices.", with all options greyed out. Huh!? Confused.
I then went all out and uninstalled the Creative and Soundmax drivers and utilities completely, rebooted, and installed them both again afresh between reboots. Still no luck: Same errors. I also tried switching the PCI slot for the audio card as the previous slot was directly underneath the graphics card, but this didn't do the job.
Does anybody have a way out of this nightmare? I know a reformat is a solution to all problems, but I'd really like to avoid it right now, if at all possible.
Thanks.
