Simultaneous output with PipeWire

Hello,

I’m trying to setup simultaneous output of sound on my laptop. I’m trying to merge the builtin audio stereo and a bluetooth headset. With pulseaudio, I usually run paprefs and set the simultaneous output checkbox, then the new simultaneous sink becomes available in pavucontrol.
However, using pipewire and pipewire-pulse, paprefs crashes with this error:

$ paprefs

(paprefs:15405): GLib-GIO-ERROR **: 15:44:00.778: Settings schema 'org.freedesktop.pulseaudio.module-group' is not installed
[1]    15405 trace trap (core dumped)  paprefs

Is there simply a file missing from pipewire-pulse? Or something deeper?
How can I achieve simultaneous output on PipeWire?

Thanks.

Re: Simultaneous output with PipeWire

You need to manually load dummy sinks and link them up correctly. The functionality that paprefs relies on in pulseaudio isn't implemented in that form in pipewire, see this previous thread for pointers, in particular the last post for a real example and the others for a bit of background info on why this is necessary: https://bbs.archlinux.org/viewtopic.php?id=261484
