Pipewire and airplay

Hi all, first of all, I love NixOS.

I had a question about the pipewire configuration for airplay as explained in the wiki: PipeWire - NixOS Wiki

Now, this works as expected for me, I can see the airplay device in pavucontrol. But I’d like this to be more like how I connect to airplay devices on my iphone: eg. select the device/activate the device on demand.

Currently, with the module enabled, my computer connects to the airplay host. Other devices cannot connect to it even if there’s no playback on the computer. I’d like to enable the module but only activate it on demand.

Is this possible? I understand this may not be NixOS specific. Thanks.

I’m unable to see anything relevant in the pipewire docs either, PipeWire: AirPlay Sink
I’m sure this is a common problem.
