I have 4 Sonos Ports in my set up, all Ethernet wired to my network. I use my phone to play music to them, usually uttering “Siri play some music in the Backyard” (Backyard is the name of a port, in the room “Backyard” of my Apple Home set up). I also have tried picking a port in the output selector.
In both of these scenarios, I see about 25% of the time, that Siri will say “OK” or the route is changed successfully in the picker, but then nothing is rendered on the speakers, even though the Apple Music playhead is moving as if nothing is wrong. I have checked my amp, my network, etc. and everything is fine.
Interestingly, to recover, all I need is to turn off that route in the picker, and then selected it again, and immediately music is rendered. This leads me to believe it is an iOS issue, but I cant confirm. Has anyone else experienced this? It has been going on ever since I’ve had the ports, ~2 years or so.
Since it isn’t 100% repeatable, it is slow to debug. I think it has something to do with the amount of time in between usages, e.g. if there is a long time between when I use a Port, maybe it goes to sleep and there is bug on wake that causes rendering failures. Just guesswork, as I said, it is hard to repro on demand.
