My default way of playing movies, is via my RPi 4 running OSMC. Next to that, I have been playing around with a FreeDSP Aurora DSP for a while. In Windows 10 and Ubuntu, this device is automatically recognized as an 8 output channel audio device. However, OSMC doesn’t seem to see it when I connect it. It only lists the 2.0 channel output of my TV that is connected via HDMI.
Would it be possible to add support for the Aurora DSP?
