No Audio on AirPlay 1 Device (raop, latest master)

  • PipeWire version (pipewire --version): latest master (commit hash: baa54976):
  • Distribution and distribution version (PRETTY_NAME from /etc/os-release): Manjaro ARM
  • Desktop Environment: Phosh
  • Kernel version (uname -r): 6.3.8-1-MANJARO-ARM

Description of Problem:

I cannot play audio on my AirPlay 1 JAM Symphony speaker. When I try to select it in my system sound settings app or pavucontrol, my selection reverts to the previously-selected audio device. I cannot tap the speaker in the GNOME "audio test" window. Forcing audio redirection with pactl just silences sound until I select a different output device.

How Reproducible:

Every time

Steps to Reproduce:

To force the device to try to play audio out of it, I started an instrumented libpipewire-module-raop-discover instance as follows:

PIPEWIRE_LOG_SYSTEMD=false PIPEWIRE_DEBUG=*:3,mod.raop*:5,pw.rtsp-client*:5 ~/remote_gui.sh pw-cli -m load-module libpipewire-module-raop-discover raop.latency.ms=5000

Then, I explicitly redirected audio to it while playing a video in Firefox as follows:

[nicholasroth@manjaro-arm pipewire]$ ~/remote_gui.sh pactl list short sinks
43	raop_sink.Sonos-347E5C9D632F.local.ipv6	PipeWire	s16le 2ch 44100Hz	IDLE
45	raop_sink.Sonos-347E5C9D632F.local.ipv4	PipeWire	s16le 2ch 44100Hz	IDLE
46	raop_sink.JAM\032SYMPHONY_4898-2.local.ipv4	PipeWire	s16le 2ch 44100Hz	RUNNING

721	raop_sink.Sonos-347E5C9D632F.local.ipv4	PipeWire	s16le 2ch 44100Hz	IDLE

[nicholasroth@manjaro-arm pipewire]$ ~/remote_gui.sh pactl list short sinks

46	raop_sink.JAM\032SYMPHONY_4898-2.local.ipv4	PipeWire	s16le 2ch 44100Hz	IDLE
80	alsa_output.platform-rt5640-sound.HiFi__hw_PinePhonePro__sink	PipeWire	s24-32le 2ch 44100Hz	IDLE
721	raop_sink.Sonos-347E5C9D632F.local.ipv4	PipeWire	s16le 2ch 44100Hz	IDLE
722	raop_sink.JAM\032SYMPHONY_4898-2.local.ipv4	PipeWire	s16le 2ch 44100Hz	RUNNING
723	raop_sink.Sonos-347E5C9D632F.local.ipv6	PipeWire	s16le 2ch 44100Hz	IDLE

Actual Results:

  • The GNOME GUI and pavucontrol indicate an inability to connect by not unselecting the current audio output device when I try to switch outputs
  • When I force it to stream to an instrumented libpipewire-module-raop-discover instance with pactl move-sink-input, the sound just goes quiet until I kill the instrumented instance and sound reverts to the device speakers

Expected Results:

When I try to select my JAM Symphony smart speaker as an output device while watching a video, the sound should play out of the smart speaker.

Packet Captures:

I am attaching packet captures from both pulseaudio (working) and pipewire (not working) here. Note that during the pulseaudio packet capture, sound played for ~1s on the device, then firefox no longer registered as an audio source in pactl. I de-selected and re-selected the speaker in the Settings app, restarted Firefox, opened the video again, and it played normally. I recorded all of that in the pcap file. The pipewire test followed the procedure in "Steps to Reproduce".
