I don’t know what’s going on here. My sound was fine, but my computer hung up after a network glitch while accessing a network drive. On restart the sound icon has a red x and a message ‘No Audio Output Device is installed’.
I went back to the recovery point which amazingly was just the day before, but the fault still occurs.
I’ve uninstalled and reinstalled the drivers many times to no avail.
My virus scans appear clean including the malwarebytes one I’ve just done.
It’s a Compaq Presario CQ61 laptop running Windows 7 SP1
Device manager shows errors on the High Definintion Audio devices with message:-
‘Windows cannot start this hardware device because its configuration information (in the registry) is incomplete or damaged. (Code 19)’
I’ve uninstalled and reinstalled the drivers using Windows and also HP.
CCleaner is doing a pretty decent job.
Don’t know if it will be enough though, but give it a try.
Run the scan for registry issues multiple times till nothing is found anymore.
After each scan, have CCleaner fix the things.
When nothing more is found, reboot and run CCleaner again.
