Hi!
Fedora 38 (6.5.6-200.fc38.x86_64 )
wireplumber: Compiled with libwireplumber 0.4.14
pipewire: Compiled with libpipewire 0.3.81
So i try to Simultaneous output to multiple sinks on the same sound card.
Found this Article: WirePlumber - ArchWiki
And under 2.6 ( Simultaneous output to multiple sinks on the same sound card) my Scenario is described. (i thought …)
So i tryed that.
But it doesnt work (only one connected and selected Sink gets Sound)
Before doing the described scenario i only could select one Sink in pavucontrol.
After that all my Sinks are selectable → so that was progress but not what i was expecting.
I dig deeper and i think what the Wiki Article describes is not correct or i dont understand it correctly.
I think output-mappings = analog-stereo hdmi-stereo does not what the wiki describes.
Couldnt find another source of “multiple describe sinks in output-mappings”.
And on the other hand this is the ALSA card profile configuration file, which are used to define the characteristics and not linking sinks.
so after digging even deeper i think this needs to be done in wireplumber.
After i couldnt make this work with googling around i ask chatgpt.
His idea was a wireplumber Policy for routing a Stream to the Sinks.
But it doesn’t work or I’m not doing it correctly.
The documentation doesn’t help me either.
lets get technical.
First i checked if the Outputs are working Kernel Side

check wireplumber (if we now have all (2) sinks)

2 Sinks available (the third one we saw earlier is not connect for testing purpose).
Before doing the steps above i only could see one sink in wpctl status.
create a wireplumber Policiy
Note: i checked for correct media-names and node-name with pactl list sinks and even tryed some variations.
vim /usr/share/wireplumber/policy.lua.d/15-chromium-sink.lua
policy = {
{
{
matches = {
{
{ "media.name", "==", "Playback" }
}
},
actions = {
{ type = "route", path = "alsa_output.pci-0000_00_1f.3.analog-stereo" },
{ type = "route", path = "alsa_output.pci-0000_00_1f.3.hdmi-stereo" }
}
}
}
}
i rebooted after or just restarted wireplumber (and chromium) with systemctl --user restart wireplumber
but it doesnt work. (only output on one sink)
wireplumber error log
i cant find relevant logs for my policy.
Don’t know if the policy gets used or is correct either …
After a wireplumber service restart journalctl shows:

workaround test 1
using pactl load-module module-combine-sink creates the combined sink.
if i manually set my Chromium to this sink in pavucontrol its outputing to all devices.
But how to do this with wireplumber directly and automatically.
workaround test 2
As described here Configure audio for simultaneous output? - #7 by Merritt
(Thanks @Merritt )
pactl load-module module-null-sink media.class=Audio/Sink sink_name=my-combined-sink channel_map=stereo
Start qjackctl and under “Graph” link the connections.
Couldnt figure out yet how to make this change permanent.
But what is qjackctl doing under the hood?
This has to be working directly with wireplumber - right?? RIGHT GUYS???
