The drivers just stop working. had that issue with 14393.939 as well BEFORE the Creators Update.
The driver stops working for whatever reason. uninstalling the 2+ driver and reinstalling does work but I'm tired of reinstalling it.
I can change from the different modes, movie to the others and can hear the changes but, now as it usually does, it doesn't change the quality of the sound. added: sound quality is completely lost as well.
Please fix this!
