Hi all, (This is an edited version sent to Tanu before I knew about this mailing list) I hope someone here can help. I understand that previous versions of Pulseaudio < 11 had the ability to connect to older Airport Expresses in order to use the Airplay function. I read that due to newer devices using UDP rather than TCP the Airplay functionality wouldn't work with these new devices. I know that someone did their own patched version for RAOP 2 - https:/ /hfujita.github.io/pulseaudio-raop2/ - I never tried this patch. However, when I read that the new Pulseaudio 11 includes these changes and that it should now work, I got really excited. However, I'm having the exact same problem that I did before. I enable Airplay discovery in PA-prefs, and GNOME Sound Settings detects my Airport Express (it's listed twice for some reason). However, when I select one of them and use the Test Speakers function, no audio can be heard. All volume sliders are on full. Playing a track using Audacious for example, whilst Airport Express is selected for output, results in no activity at all, the track doesn't even begin to play, with the track time stuck at 0:00:00. Switching back to Built-in Audio works fine. I'm using a fully updated Arch Linux and Pulseaudio 11.1. I have no password set on my Airport Express and it works fine using iTunes on my Mac (which I make sure is disconnected before trying it on my Linux PC). With Tanu's help, I managed to get some log output from PulseAudio to see what was going on. In terminal 1: pulseaudio -vv - seems to start normally. In terminal 2 : pactl load-module module-raop-discover" I won't post the full log here, but the meaningful messages seem to be: I: [pulseaudio] client.c: Created 4 "Native client (UNIX socket client)"D: [pulseaudio] protocol-native.c: Protocol version: remote 32, local 32I: [pulseaudio] protocol-native.c: Got credentials: uid=1000 gid=100 success=1D: [pulseaudio] protocol-native.c: SHM possible: yesD: [pulseaudio] protocol-native.c: Negotiated SHM: yesD: [pulseaudio] protocol-native.c: Memfd possible: yesD: [pulseaudio] protocol- native.c: Negotiated SHM type: shared memfdD: [pulseaudio] memblock.c: Using shared memfd memory pool with 1024 slots of size 64.0 KiB each, total size is 64.0 MiB, maximum usable slot size is 65472D: [pulseaudio] srbchannel.c: SHM block is 65472 bytes, ringbuffer capacity is 2 * 32712 bytesD: [pulseaudio] protocol-native.c: Enabling srbchannel...D: [pulseaudio] module-augment-properties.c: Looking for .desktop file for pactlD: [pulseaudio] protocol-native.c: Client enabled srbchannel.I: [pulseaudio] module.c: Loaded "module-raop- discover" (index: #24; argument: "").I: [pulseaudio] client.c: Freed 4 "pactl"I: [pulseaudio] protocol-native.c: Connection died.D: [pulseaudio] module-raop-discover.c: Found RAOP: John's AirPort ExpressD: [pulseaudio] module-raop-discover.c: Found key: 'txtvers' with value: '1'D: [pulseaudio] module-raop-discover.c: Found key: 'ch' with value: '2'D: [pulseaudio] module-raop-discover.c: Found key: 'cn' with value: '0,1'D: [pulseaudio] module-raop-discover.c: Found key: 'et' with value: '0,4'D: [pulseaudio] module-raop-discover.c: Found key: 'sv' with value: 'false'D: [pulseaudio] module-raop-discover.c: Found key: 'da' with value: 'true'D: [pulseaudio] module-raop- discover.c: Found key: 'sr' with value: '44100'D: [pulseaudio] module- raop-discover.c: Found key: 'ss' with value: '16'D: [pulseaudio] module-raop-discover.c: Found key: 'pw' with value: 'false'D: [pulseaudio] module-raop-discover.c: Found key: 'vn' with value: '65537'D: [pulseaudio] module-raop-discover.c: Found key: 'tp' with value: 'TCP,UDP'D: [pulseaudio] module-raop-discover.c: Found key: 'vs' with value: '105.1'D: [pulseaudio] module-raop-discover.c: Found key: 'am' with value: 'AirPort10,115'D: [pulseaudio] module-raop-discover.c: Found key: 'fv' with value: '76800.1'D: [pulseaudio] module-raop- discover.c: Found key: 'sf' with value: '0x4'D: [pulseaudio] module- raop-discover.c: Loading module-raop-sink with arguments 'server=[169.254.13.13]:5000 sink_name=raop_output.Johns-AirPort- Express.local sink_properties='device.description="John\'s AirPort Express (169.254.13.13:5000)"' protocol=UDP encryption=none codec=ALAC channels=2 format=16 rate=44100'I: [pulseaudio] module-device- restore.c: Restoring volume for sink raop_output.Johns-AirPort- Express.local: front-left: 47452 / 72%, front-right: 47452 / 72%I: [pulseaudio] sink.c: Created sink 1 "raop_output.Johns-AirPort- Express.local" with sample spec s16le 2ch 44100Hz and channel map front-left,front-rightI: [pulseaudio] sink.c: device.string = "[169.254.13.13]:5000"I: [pulseaudio] sink.c: device.intended_roles = "music"I: [pulseaudio] sink.c: device.description = "John's AirPort Express (169.254.13.13:5000)"I: [pulseaudio] sink.c: device.icon_name = "audio-card"I: [pulseaudio] source.c: Created source 2 "raop_output.Johns-AirPort-Express.local.monitor" with sample spec s16le 2ch 44100Hz and channel map front-left,front-rightI: [pulseaudio] source.c: device.description = "Monitor of John's AirPort Express (169.254.13.13:5000)"I: [pulseaudio] source.c: device.class = "monitor"I: [pulseaudio] source.c: device.icon_name = "audio-input-microphone"D: [raop-sink- [169.254.13.13]:5000] raop-sink.c: Thread starting upD: [raop-sink- [169.254.13.13]:5000] raop-sink.c: RAOP: IDLED: [pulseaudio] module- device-restore.c: Could not set format on sink raop_output.Johns- AirPort-Express.localD: [pulseaudio] module-suspend-on-idle.c: Sink raop_output.Johns-AirPort-Express.local becomes idle, timeout in 5 seconds.D: [pulseaudio] rtsp_client.c: Attempting to connect to server '169.254.13.13:5000'I: [pulseaudio] module.c: Loaded "module-raop-sink" (index: #25; argument: "server=[169.254.13.13]:5000 sink_name=raop_output.Johns-AirPort-Express.local sink_properties='device.description="John\'s AirPort Express (169.254.13.13:5000)"' protocol=UDP encryption=none codec=ALAC channels=2 format=16 rate=44100") Then, further down: D: [raop-sink-[169.254.13.13]:5000] raop-client.c: Can't stream, connection not established yet...D: [raop-sink-[169.254.13.13]:5000] raop-client.c: Can't stream, connection not established yet...D: [raop- sink-[169.254.13.13]:5000] raop-client.c: Can't stream, connection not established yet...D: [raop-sink-[169.254.13.13]:5000] raop-client.c: Can't stream, connection not established yet...
