Since installing a Windows 10 Update (and also an updated Audio Driver from I/O Bit at about the same time) I have lost all Audio. The message I get is "No Audio Output Device is installed". I/O Bit have been very helpful in attempting to resolve this problem, but so far without success. None of the automated solutions from HP or Microsoft have been able to identify or rectify this problem. Has anyone got any advice? Thanks.
I also installed and ran the HP Hardware Diagnostics utility (pressing F2 at boot) and test the audio, and in my case I also got audio through both headphones and speakers. HOWEVER, the system still says "No Audio Output Device is installed"! When I attempt to play any Audio there is NOTHING! At least I may be a little bit nearer a solution. Thanks for your help anyway,
