Is it possible to enable HDMI audio when running an UWP app on RPi 2? There is sound when I connect speakers via the 3.5mm jack, but I would prefer HDMI audio.
Apparently it's possible, but I don't know how to do it on IoT Core: https://www.raspberrypi.org/documentation/configuration/audio-config.md
HDMI audio is not supported on Windows 10 IoT for the Raspberry Pi. The only option available is the 3.5mm headphone jack.
