I wonder if anyone else has had this problem. Yesterday my Surface 3 was not able to play any sounds. The speaker set up widget gave a unhelpful "There was an error" message. The Microsoft support site, in the self help section, ran the sound trouble shooter and then the hardware and drivers trouble shooter. The hardware and drivers trouble shooter pointed out that the AC3 driver was not fully installed. It fixed it, and life goes on. This isn't the first time this has happened though. I had to reinstall the all the sound drivers after another update. Am I alone? All these finicky little problems on my Surface 3 are like sleeping with mosquitoes. It really takes the fun out of it.
