Using WindowsIoT on the Raspberry Pi 3 I tried playing sound/video from a c# application. The video plays, however the sound is played over the 3.5mm jack instead of over HDMI. It's an older TV, so maybe it isn't detected automatically, but the TV does have speakers.
How can I switch the sound output from jack to HDMI with WindowsIoT like you can switch it with Raspbian?
