Right after a lot of searching and asking, the issue seems to be: shairport supporting airplay 2?
According to the pipewire devs, for now they only support airplay 1.
Unfortunately... this seems not to be a configurable item for shairport, you need to set the airplay protocol at build time: see here, search for airplay 1 or classic mode
so I'm asking just to verify: shairport in moode is build with airplay 2 activated?
thanks

Correct, AirPlay 2.

Ok, just to document this issue: I rebuilt shairport on moode with airport1 Protocol enabled, and unfortunately the issue still looks the same.
the log from shairport:

Based on that result do you think its something that still needs investigation on our end?

Hi Tim,
according to the pipewire people. using airplay 1 should have worked, whereas airplay 2 should definitly have not.
At the moment I am honestly not sure where the problem lies

It doesn't seem to me that moOde is doing anything special with shairport-sync but I suppose one diagnostic is to set up a minimal AirPlay receiver on a Pi with Bookworm RaspiOS Lite and shairport-sync to see if the stuttering is still present. There are any number of HowTos out there on the InterWeb™.
You could also ask Mike Brady, the shairport-sync maintainer, if he has any suggestions beyond the one he already made to another user. (I tried to search his issues log but since the word PipeWire appears in his standard form for posts, it's really hard to get just the past PipeWire-related issues.)
Finally, there's still Mike's suggestion of trying OwnTone as an alternative to pipewire/raop.
Regards,
Kent

Thanks Kent.
I made an ticket at shairport; let's see what happens.

Just a quick update: in the issue above, someone commented that apparently for them it is also not working with a raspberry pi in the equasion.
Just for me to know: do people actually use moode over shairport/airport?
As shairport was for me an alternative solution to a problem, maybe as an update: The developer of pa-dlna has adjusted his project, and now it also works with upmpcli and therefore with moode. I built a package for my computer to have it run as a user service, so I can just stream directly to moode over pa-dlna now. If anyone is interested in this solution, drop me a line.

I often exercise shairport-sync from my Apple iPad. Works a treat.
Using non-Apple sources is another matter. I don’t even try.
