Hi, I updated my laptop from windows 8 (when sound worked fine) to windows 8.1 where it doesn't.
If I go to the control panel and unistall the realtek drivers, then re-install them the sound works, that is until I switch off (yes I know - don't switch off then :-) ).
When the computer restarts there is no audio....again. the only way I have found toget it working is the uninstall - re-install of the drivers. It's driving me mad.
Any ideas anyone??
