I've been troubleshooting the issue with Mike at shairport-sync here: https://github.com/mikebrady/shairport-sync/issues/2031
In my debugging, it appears that the audio output is being blocked by something waiting on timedated service. When this service terminates, playback finally begins.
@Tim Curtis Any guesses on what could be the culprit? I haven't been able to trace down which processes are responsible.
I changed the tag back to "Problem".
I'll give the Git issue a read and do some poking around to see if I can gain any insights into what might be happening.

Also, prolly a good idea to reboot one of the affected Pi's and post the startup log so we can see what the configuration looks like.

I'm not able to repro the "delayed audio" issue but below is some output from journalctl when my iPhone starts playback to moode AirPlay receiver. The audio is heard almost immediately after tapping the play button.
Note the ~30 sec time period between "Started" and "Deactivated"
Code:

Here is a summary of key information which might be useful in debugging this:
- Occurs on both pi-3B+ and pi4
- Only happens when airplaying from iphones (verified with 14Pro and 12mini) (airplaying from macbook and iPad does not exhibit this issue)
- Seems to be resolved when systemd-timedated.service terminates
- Network is dual stack ipv4 and ipv6 (may or may not be relevant)
- Pi is connected over wi-fi (i'm not able to run ethernet to its location)
Things I have tried without success:
- Turning off sonos which is on the network
- Disabling the run_this_before_entering_active_state and run_this_after_exiting_active_state scripts
- Disable ipv6 announcements for mDNS
- Disabling other renderers I have installed (plexamp and roonbridge)
I could do a packet capture on the Pi and on my iPhone, but I don't have the knowledge to be able to say if what is happening is probelematic or not.

I don't see anything suspicious in the moode log.
In the absence of a "smoking gun" and since the issue only occurs on your iPhone (other clients are ok) I would try to rule out a network issue for example the iPhone should be on the same IPv4 subnet 192.168.219.x as the Pi and connected to the same WiFi access point as the other clients that don't exhibit the issue.
If a network issue can be ruled out then if possible try someone else iPhone and see if the 30 sec play delay occurs.
RE: Airplay No Sound Output - christopherr - 06-26-2025
Yeah, all devices are on the same subnet. There is a firewall on the WAN, but no firewalls on the internal LAN.
I have disabled the IP anonymisation features on the iphones (limit IP Address tracking and Private WiFi mac addresses) with no success.
