Multiroom receiver crashes

You might want to update to 9.1.4 to get rid of all the DEBUG log spam.

Is your AVR on when the Pi boots?

Tried this experiment:
1) AVR on, Pi On, Multiroom music on
2) Triggering Pi Restart
3) Pi starts up, plays multiroom music
4) De-Select this Pi on server
5) Switing AVR off
6) Select this Pi on server again
7) Watchdog errors
8) Switch AVR on
9) Still Watchdog errors appearing

And this one (see point 4 - keeping the multiroom transmission on)
1) AVR on, Pi On, Multiroom music on
2) Triggering Pi Restart
3) Pi starts up, plays multiroom music
4) De-Select this Pi on server
5) Switing AVR off
6) Select this Pi on server again
7) Watchdog errors 
8) Switch AVR on
9) Still Watchdog errors appearing
10) plays multiroom music

The first scenario is understandable because the AVR has to be on first before the receiver is started.

The second scenario seems to suggest that once the receiver acquires the audio device and starts playing, it will maintain that device reference even though the device is power cycled.

I'm not sure there is anything to be done in moode though because the general requirement for HDMI port in Bookworm videocore is that it must be connected to an audio device thats powered on before playback starts otherwise player applications will throw errors or crash because of "no audio device".

I added
require_once __DIR__ . '/audio.php';
to /var/www/inc/multiroom.php

Now I can shut down/powerup my AVR whenever I want... No more watchdog errors

Ok good find. 
I'll fix that big for upcoming 9.1.5 release.
