I suppose it's not a driver problem.
At the top of the list, there must be an "Audio inputs and outputs", and there must be devices when you unfold it.
Please go to 'Settings' >'Devices' > 'Bluetooth & other devices' > 'Sound settings' > 'Choose your output device', and choose the TV as the output device.
Let me know if it resolves the problem.
Now problem solved.
Download drivers package, unzip it.
Open device manager, right click on unknown device, manually install driver, choose unzipped driver folder, select "include subfolders".
