Does anyone here have the same problems as me? I am connected via Bluetooth, but it is recognised as the following device: "Headphones (Surface Headphones - Handsfree)" for audio output as well as input. I have installed the Surface Audio App. Is connected according to the app volume and noise cancellation is also updated when adjusting the headset. It is now also listed in the Bluetooth Device Manager as "LE Surface Headphones". But still no sound. Software is up to date - No change via USB connection. I get sound via 3.5mm jack, but that's hardly the point of using a cable... I had no problems with the Android smartphone. I also had no problems on the desktop PC with Windows 10 to which other headsets are connected. So far, the problem only exists with the Surface Pro 7 - great, isn't it?
