I'm experiencing a similar issue where MDX isn't displaying properly after standby. for me this wouldn't be a problem if MDX turned the outputs back to the "on" status.
I have the default status to "on" in order to turn on my amps when my carPC starts up.
When I shut down/ standby, the fusion brain turns off the outputs.
The Fusion brain will only turn the outputs on started from a shut down, not if resumed from standby, is there any way to do this?
