Just upgraded my Surface Pro 3 to Windows 10 and am now getting no audio on HDMI out.
I am using a genuine MS HDMI adapter for my SP3 and was using it to stream to my TV only an hour before the upgrade.
I do get video but no sound.
TV is a Sony Bravia. Don't know a lot about it other than that. It came with the apartment I am renting right now but as I said, it was working just fine an hour before the upgrade.
Any suggestions or help would be appreciated.
