Hello! I have an Apple Airport Express (1st version) and wanted to finally use its RAOP function in Linux. But I have a couple of problems with it and don't know how to get past them... so I thought, I'll ask for help. Help! My setup: 1. The Airport Express in the LAN (local, RJ45) and has a static IP 192.168.1.21. 2. The PC has another static IP 192.168.1.47, it runs Debian testing amd64. 3. The router is running pfSense (current Community Edition), provides a DHCP server and is configured with static IP addresses for known devices (a list that I manage manually). All of them are also reachable by local DNS names, i.e. "airport" is the same as 192.168.1.21. So, I installed pulseaudio-module-raop on Debian (apt install). I followed https://wiki.ubuntuusers.de/PulseAudio/AirTunes/ and also installed paprefs. Using paprefs, I checked "Make discoverable Apple AirTunes sound devices available locally". After a reboot I see TWO devices with the DNS name of my AirPort Express WLAN router. But none worked. I checked pactl list modules and found that their IP addresses are completely wrong: 169.254.145.142:5000. So I tried to load the modules manually. I removed the wrong ones with "pactl unload-module ##" (the modules number from the list) and reloaded the module: pactl load-module module-raop-sink server=airport sink_name=raop.AirPort (server=192.168.1.21 works just the same) That worked. > Modul #35 > Name: module-raop-sink > Argument: server=airport sink_name=raop.AirPort > Usage counter: 1 > Properties: > module.author = "Colin Guthrie" > module.description = "RAOP Sink" > module.version = "9.0" What did not work was to add option sink_properties='device.description="AirPort Express"' -- the module always failed to load that way. I am also not able to change its name later, using: pacmd update-sink-proplist raop.AirPort device.description="AirPort Express" only writes "Failed to parse proplist." I also tried module.description, which also failed. Anyway, I can now see the "sink" as an output choice in pacucontrol and I can make an application use this output for sound. This is partly success -- finally I got the module loaded correctly! Only, the sound doesn't work. I get parts of the sound every 2-4 seconds or so, inbetween is silence. The sound piece that comes through is about 1/3rd of a second long (or less). I see the same effect both on the output device itself (I hear the sound as mentioned: only pieces of it now and then) as well as I see the levels likewise in pavocontrol on this output sink. So I assume that the problem is in the module, or in the configuration of it or in pulseaudio configuration. My questions: 1. What should I try or what have I done wrong in the first place? 2. Is there a way to get steady sound output to the RAOP device and how do I configure this? 3. Is there a way to set the sink statically (without module-raop-discover which gets the wrong IP addresses and creates two devices with it) and to automatically set this up with the start of pulseaudio? Thanks in advance, Linux User #330250 aka Andreas
