Shairport and Pipewire

[janstadt]

Ive looked through a lot of posts here about how Pipewire and PulseAudio is problematic, but i want to be able to push audio out of one speaker from multiple sources. I use homeassistant to push notifications and airplay to play music. if they both use airplay, the session interruption isnt reliable enough for the setup and i typically get an error where the annoucement doesnt play or is truncated. Enter pipewire. I followed this post and had it working for a while, but now i keep getting this error:

Jan 31 18:24:53 the-kitchen shairport-sync[557]: warning: Shairport Sync's PipeWire backend can not get timing information from the PipeWire system. Is PipeWire running?

pipewire.service is running as a --user service as well as wireplumber.service.

I had working at one point, but now it no longer works on one of my devices (pi 3b with a hifiberry dac).

Version (built with pipewire):
4.3.5-AirPlay2-smi10-OpenSSL-Avahi-pw-soxr-metadata-mqtt-sysconfdir:/etc

Command Line:
 shairport-sync --displayConfig

Configuration File:
 /etc/shairport-sync.conf

Configuration File Settings:
 general : 
 {
   name = "The Kitchen";
   output_backend = "pw"; #i've tried with this line commented out as all i have is pw as an option and it shows pw (default)
 };
 sessioncontrol : 
 {
   allow_session_interruption = "yes";
 };
 pw : 
 {
 };

I use snapclient as my other protocol and that works still so i can get audio from there, but not from airplay. Any help would be greatly appreciated.

Ok so i figured out why the-kitchen wasnt working (somehow i hadnt disabled the system level shairport-sync so it was conflicting with the user level one.) but im still wondering about these logs about pipewire.

Thanks for this. I think it's better as an Issue, so I've opened one.
