Impressive! Thanks, that was it!

I've tried to move around ' and ", I even escaped the " (as \") and the 
whitespace, but to no avail.

This works:
pactl load-module module-raop-sink server=airport sink_name=raop.AirPort 
sink_properties="device.description=AirPort"

(This also works with ' instead of ", but neither works with a whitespace.)

Thanks!

I've added the above line as load-module in /etc/pulse/default.pa. I 
will see if it worked with the next boot+login.

The one thing that remains unclear to me so far is how it autoloads in 
the first place, because I cannot find any raop modules in the config 
files in /etc/pulse. I assume that module-raop-discover does the magic, 
but it does it wrong, so I would like to blacklist this module and 
manually load the modules-raop-sink instead. Only, I couldn't find a 
blacklist syntax for default.pa (or system.pa). I found 
"disallow-module-loading true" which prevents all module loading. I 
could try unload-module, but how will this prevent a later invoked 
automatic module loading? I hope that the manual line in 
/etc/pulse/default.pa will prevent the module-raop-discover magic from 
now on, otherwise I can only think of renaming module-raop-discover in 
the file system.


Thanks so far,
