I had no GStreamer-based players installed, so installed gst123 for a 
quick test. Result: same freeze.

Also tested with VLC, seeking there does not freeze.

With Bino, I was able to trigger this assertion failure:

E: [raop-sink-[192.168.1.39]:5000] rtsp_client.c: Assertion 'c->url' 
failed at modules/rtp/rtsp_client.c:441, function rtsp_exec(). Aborting.

Sure. And here is what "avahi-browse --all" prints:

The relevant part of the pulseaudio log is:

D: [raop-sink-[192.168.1.39]:5000] raop-client.c: Can't stream, 
connection not established yet...
D: [raop-sink-[192.168.1.39]:5000] raop-client.c: Can't stream, 
connection not established yet...
D: [raop-sink-[192.168.1.39]:5000] raop-client.c: Can't stream, 
connection not established yet...
D: [raop-sink-[192.168.1.39]:5000] raop-client.c: Can't stream, 
connection not established yet...
D: [pulseaudio] socket-client.c: connect(): Connection refused
E: [pulseaudio] rtsp_client.c: Connection failed: Connection refused

So - it is not on port 5000. This connects and pretends to send audio:

pacmd load-module module-raop-sink 'server=[192.168.1.39]:6000' 
sink_name=raop_output.Airfoil.local 
sink_properties='device.description="Airfoil-Speakers"' protocol=UDP 
encryption=RSA codec=ALAC channels=2 format=16 rate=44100

protocol=TCP causes Airfoil Speakers to crash.

All the attempts of PulseAudio to speak to Airfoil Speakers have been 
logged and attached.
