I'm struggling with the built-in setup tool / web interface. It showed up once, so I've set up the basics (and know the system is working - I also get sound and can play to the amp/speaker), but when I try to go back and adjust some parameters I'm only occasionally successful at reaching the setup area. It usually just keeps saying "Searching..." and it's getting really annoying.
What's even more annoying is that I can successfully both ssh and VNC to the Pi. So nearly everything is working - except the web interface.
I've found a json file with the settings - can I adjust them there? Or is there somewhere else I can easily adjust the (very few) settings that are in the web interface?
