Noticed this evening that for some reason my audio suddenly went kaput – volume icon in the system tray was showing with a red X though it, saying “no audio device detected”. A quick look around in Device Manager showed the audio driver not listed, and Scan for new hardware detected nothing. Tried many options (like downloading the drivers from the Dell site, they wouldn’t install because – you guessed it – no audio device was present!). Booted into the Dell Utility Boot, audio tests failed with a message about timeout while waiting for the adudio controller to generate an interrupt…..

Here’s what (finally!) fixed it:

1. Reboot and go into the BIOS setup
2. Disable the onboard integrated audio and continue to boot into Windows with no audio
3. Reboot
4. Go into BIOS setup again end now enable integrated audio, and presto! sound works perfectly.
