This was without any Sound blaster software installed. Now when 1709 completed I had sound for the first time AFTER a shutdown and cold boot.
I would then reinstall drivers and would get the green bars in volume mixer but still no sound and very slow video streaming, again with no sound. So my problem consisted of Sound Blaster Z either producing no sound with no sound signal visible in volume mixer which was often accompanied by slow video streaming or none at all. I Deferred updates for 2 years but when 1709 was pushed it circumvented my deferment so I decided to give it a try before the customary Rollback of the OS to 16**. My Sound Blaster Z would produce no sound after Windows 10 creators and anniversary updates. This is the first post I have made and hope it helps because I have had this problems for over 2 years.
