Hi,
I have a MiniDSP U-DIO8
<https://www.minidsp.com/products/usb-audio-interface/u-dio8> connected
to the USB port of a 2018 Mac Mini running Kodi 18.1-RC1 on Mojave
10.14.4. The U-DIO8 provides 8 output channels as 4xSPDIF connections
and similarly 8 channels of input as 4xSPDIF connections.
I can capture audio input from the input channels but I do not know how
I can stream ffmpeg output to the U-DIO8 output channels.
If I list devices this is what I get:
~#ffmpeg -f avfoundation -list_devices true -i ""

The USBStreamer is the U-DIO8 device.
What do I need to add to the ffmpeg command line to cause ffmpeg to
output to USBStreamer?
Thanks,
