I bought the Coolstar SOF audio driver for my Acer Chromebook 315 with a Celeron N4500 processor. But when I install it, I get an error in Device Manager with a question mark icon, and there’s no sound. What can I do?
did you activate the license as per the driver readme?
you can right click/choose Properties to see why the device has an error, I’d wager it’s due to license activation
Go to https://coolstar.org/chromebook/driverlicense/ and login..
