Samsung Series 5 550 Touchpad and Speakers not working

I recently installed win 10 on my Chromebook, I installed all librares and drivers that were available in Coolstar’s guide, but the Touchpad and the Speakers are not working at all. There’s a driver available for the Touchpad, but installing it doesn’t fix the issue.

Run windows update, install all optional updates, try re-running the script to install dptf drivers. Make sure you are connected to WiFi when you do so
