Windows 10 - No Sound - Code 10 for Intel Smart Sound Technology device drivers

Hi there, I am on an Acer Swift 3 Windows 10 . I randomly lost sound this morning. I made sure I was all up to date with Windows Update.

Device Manager > Sound, video, and game controllers \- The only thing listed here is my Bose speaker controller. \- I used to have a RealTek Audio controller here.

Device Manager > System Devices \- Intel Smart Sound Technology (Intel (R) SST) Audio Controller has a yellow error triangle. \- I clicked on Update Drivers and I get a Code 10.

I have no idea what to do anymore. I checked the Acer website and ensured I had the latest Realtek Audio driver installed.

If anyone can help, that'd be greatly appreciated.
