My PC did an automatic update (Windows Creators - update 1703) few days ago and it had as a result the Realtek audio driver to disappear.
When I check the Device Manager, there is nothing under the "Sound, video and game controllers" and under the "System devices" the High Definition Audio Controller has a yellow triangle.
I tried to update, uninstall and re-install different versions of the High Definition Audio driver but nothing worked. My last attempt was to roll back to the previous update and try to install the driver, but with no result again.
I hope I will get some help here, otherwise I will have to re-install Windows
