I've installed the latest Windows 10 IoT Insider Preview build on the Dragonboard 410c. I've also connected the Audio Mezzanine Board and am now trying to get audio input & output through the headphone jack using a splitter for microphone and headphones.
I wrote a small UWP app to see all audio devices and I only get these two:
Speaker: Speakers (QCAUD Real Time (WaveRT) Driver for Qualcomm SoC)
Microphone: Internal Microphone (QCAUD Real Time (WaveRT) Driver for Qualcomm SoC)
I also only get the onboard microphone to work.
Do I have to activate the Audio Board / headphone jack somewhere on the hardware or software side?
