After checking in https://github.com/masmu/pulseaudio-dlna/blob/master/pulseaudio_dlna/pulseaudio.py and finding https://gist.github.com/saivert/25bff8f1d63167c7880fff654a0f3e0e it was easy to retrieve the Pulseaudio socket from PipeWire with

$ systemctl --user status pipewire-pulse.socket
● pipewire-pulse.socket - PipeWire PulseAudio
     Loaded: loaded (/usr/lib/systemd/user/pipewire-pulse.socket; enabled; vendor preset: enabled)
     Active: active (running) since Sat 2021-04-24 19:21:34 CEST; 5h 2min ago
   Triggers: ● pipewire-pulse.service

     CGroup: /user.slice/user-1000.slice/[email protected]/pipewire-pulse.socket

Apr 24 19:21:34 pons systemd[2375]: Listening on PipeWire PulseAudio.

and then injecting it into pulseaudio-dlna with monkey patching /usr/lib/python3.9/site-packages/pulseaudio_dlna/pulseaudio.py:

$ diff /usr/lib/python3.9/site-packages/pulseaudio_dlna/pulseaudio.py.before /usr/lib/python3.9/site-packages/pulseaudio_dlna/pulseaudio.py
101a102
>             '/run/user/1000/pulse/native',

et voilà, we're up and running:

Unfortunately the device will not show up in pavucontrol as of now, which may need further investigation.

Fedora 33
PipeWire 0.3.24
copr:copr.fedorainfracloud.org:cygn/pulseaudio-dlna 0.6.1

from pulseaudio-dlna.

It's something that should be resolved at pipewire level - They do promise 100% pulse compatibility, but it isn't there yet. There is
still some missing module equivalents etc - see here https://gitlab.freedesktop.org/pipewire/pipewire/-/issues/543
(F33 here, I haven't made to switch to pipewire-pulse yet, so thx for early testing !)

In the meantime, to switch back to regular pulseaudio in fedora 34:

dnf swap --allowerasing pipewire-pulseaudio pulseaudio

from pulseaudio-dlna.

There's another regression on early testing this a pre-1.0.0 pipewire release. When running pulseaudio-dlna there is also 100% CPU usage on pipewire-pulse and journald, since there are more than 10.000 events per second logged, which makes it kind of hard to debug by manually checking the log. First we get this line, and then the one below just repeats over and over again, until the unit is restarted:

Mai 01 18:24:56 pons pipewire-pulse[2610]: pulse-server 0x555a3fb3efc0: client:0x555a40b22f90 [(null)] error -95 (Operation not supported)
Mai 01 18:24:56 pons pipewire-pulse[2610]: pulse-server 0x555a3fb3efc0: client:0x555a40b22f90 [(null)] error -5 (Input/output error)

Seems this is also asking for an issue upstream, since behaviour can be reproduced with:

$ systemctl restart --user pipewire-pulse
$ id=$(systemctl show -p InvocationID --user --value pipewire-pulse); journalctl INVOCATION_ID=${id} + _SYSTEMD_INVOCATION_ID=${id} -f

and in another terminal

$ pulseaudio-dlna (--debug)

Here's their homework:

As a temporary alternative (for chromecast), mkchromecast works with pipewire. I only got it to work with python3.8 tho.

Now that this has been merged upstream, I'll just need to wait for a PipeWire version with module-loopback present to be downstreamed by my distribution, and I should be ready to go with pulseaudio-dlna again?

Then we have a quick and dirty test for compatibility:

$ pactl load-module module-loopback
Fehlgeschlagen: Entität nicht vorhanden

The same command could also help to identify the PipeWire Pulseaudio socket in another way:

$ pactl info | head -n 1
Server-Zeichenkette: /run/user/1000/pulse/native

Is this deterministic, do they retrieve this information from DBUS? How could pulseaudio-dlna leverage a similar discovery mechanism to also find Pulseaudio sockets in other locations, other than currently expected?

An update from Fedora 33, where pipewire version 0.3.25 recently landed.

As of https://gitlab.freedesktop.org/pipewire/pipewire/-/commit/e7b04bca2c7f22b2db9f8c3c6da48bd724c38c31 the patch is available in that version. Click the three little dots next to parent ... master and 0.3.25 shows up.

I can also verify that the loopback module is working with

$ pactl load-module module-loopback
262144

which has the loopback appear in the Playback tab of pavucontrol, and generates a fancy feedback loop on the speakers, if the microphone is unmuted.

$ pactl unload-module module-loopback

then helps to get silence again. So off we go to test the interface with pulseaudio-dlna again:

This does not lead to the device appearing in pavucontrol to be selectable as sink.

After these four cycles, pulseaudio-dlna returns to discovering devices:

What is interesting here, is that the three endpoints that drop their connection, are equally accessible with curl:

We have a response from upstream about:

When running pulseaudio-dlna there is also 100% CPU usage on pipewire-pulse and journald

that reads as follows:

seems to fail gracefully with master. It tries to load module-dbus-protocol, which is not implemented.

Seems we're getting there, eventually.

In the meantime, to switch back to regular pulseaudio in fedora 34:

dnf swap --allowerasing pipewire-pulseaudio pulseaudio

I know, thank you
