Acer Chromebook CP713-2W - i7 10th Gen

Despite in*stalling the SOF audio from Coolstart, the audio is still not functioning. Can you assist me in resolving this issue?

you followed the instructions to generate a unsigned file (from target chromebook?) - then bought a license and uploaded to Coolstar’s license portal?

This should give you a signed license file that can be placed in C:\Windows\System32\Drivers (or use the GUI that came with the drivers) – reboot
