Thank you for the quick reply.
Can you confirm the problem does not occur with touch display plugin disabled?
Yes. Not only that, but the Web UI works perfectly under every tested condition. The issue of switching among multiroom doesn’t occur with or without the display on if using the Web UI.
Correct - not official Pi screen, but:
- Switching it to 0 did not change the orientation. (I think I set it for 180 to see if I could get the screen to reload and then forgot I had done so.)
- Switching it back to zero does not prevent the problem on the touch screen.
Also, it looks like one other user had this in a previous version. See VOLUMIO 2.348 MULTIROOM SWITCHING VIA WEBINTERFACE - #8 by charlyarg (reply by ed733).
It appears to me that the browser kiosk on the touch screen reloads quickly when you switch to another multiroom device (as does the web UI) but the reload progress bar at the top of the screen moves much more slowly, and never finishes – the bar gets stuck near 100% – when you try to switch back to the home device on the touchscreen - the screen darkens and the spinner appears - it behaves as though a connection has been lost although the Volumio is still reachable via the web.
Again, many thanks for looking into this.
