Windows 10: Speaker/sound issue following 1709 upgrade

Tomseys, thanks for your help - I'm coming to the conclusion this is far from simple!

It's an Acer Aspire SW3-013. When I look in Device Manager for Sound, video and game controllers there are two things present: Intel SST Audio Device and Realtek I2S Audio Codec. Nothing else. No HD Audio etc. Everything worked like a charm until I had to do a re-install of Win10 to get the 1709 version in place.

 

Looks like your laptop has intel HD integrated graphics. Seems like it originally came with Windows 8.1 32 bit.

Question: Did you update to a 32 bit version of Windows 10? Seems like your system is 32 bit.

Added: I believe the Platform Drivers: "Master Installer (BIOS 1.10 + Platform driver included)" and updating to it is mentioned a time or two in the Acer support forum (see below) with regards to fixing things not working after win 10 update:

Added: Here is another solution someone posted (but for anniversary update):

Might also pay to make a post about the issue in the Acer forum to confirm best way forward.
