Realtek HD Universal Audio Service

[Mrmatt1]

Yesterday, via the HP Support Assistant, I downloaded and applied an update for the Realtek HD Universal Audio Service driver.

However, apparently there was a problem yesterday.  I have looked in Reliability History, and obtained the details of it:

Open Device Manager (search in Start menu), expand "Sound, video and game controllers," right-click "Realtek High Definition Audio" (or similar), select Properties > Driver tab > Roll Back Driver if available, then restart. This reverts to the pre-update version, resolving post-HP update hangs.

Will try that, thanks for that advice.

I will let you know the outcome.
