Hi Silver
The latest Windows update seems to have a bug in it, lots of users are reporting loss of audio after the latest Update
The fix is to go to the support page for your device on the manufacturers website, then download and install the audio device drivers they recommend, those will be compatible with your PC, unlike the ones installed by Windows Update . . .
More than likely on the manufacturers website, rather than Intel Hi-Def Audio, that is Realtek High Definition Audio
