Just got the automatic WU for Win 10 version 1607 for x64 -KB 3194798.
A restart for the completion of this automatic update followed.
The sound failed again.
This has happened for the third time.
All commenced following the Win 10 version 1607 got installed on the 22/09/2016.
Since then on every time WU provides an update -automatic update sounds stops working on my Desk top (Dell 9200) that has Creative SB X-Fi extreme sound card.

Does anyone else having this issue?
Is there any fix available to prevent this in future happening after an automatic WU?
