I’ve done a bit more digging, using atvremote, and by listing features, I can see that PlayUrl is not supported. On the other hand, I can get it to play using stream_file. Is there a way to change what method the media player uses to cast to homepod?

Okay so all this thing is a bit over my head, but from what I’m getting, the heartbeat fails.

pyatv/protocols/airplay/remote_control.py:82 - that _failure_func is the only invocation of pyatv.protocols.raop.raop.ControlClient.connection_lost that doesn’t check for None

The last heartbeat I’m seeing isn’t consistent, but it’s in the first 15-ish.

2022-11-29 23:44:18.020 DEBUG (MainThread) [pyatv.core.protocol] Got heartbeat 9 (AirPlay:xxx.xxx.xxx.xxx)

Which empirically makes sense, as I’m hearing a tiny under-half-second-long purr when I hit play. Looking at the logs, I assume the first packet of data had just been sent, then the HomePod sends back the 520. Weird that it works on my Raspberry Pi but not on the Pi inside docker :-?

Anyway, that’s all my tired neuron can figure out for now, hopefully @postlund or one of the other contributors can make sense of this.
