How to import Pulseaudio settings to Pipewire?

If you’re not using Pulseaudio manual settings, but an automatic detection, there is no reason to follow this. Just install manjaro-pipewire package and be happy without fear :slight_smile:

Instead, if you have the same problem as mine on Pulseaudio (2 inputs been used as 1 input with 2 options instead of… 2 inputs) and want to go to Pipewire, see the spoiler:

How I did with my Pulseaudio settings on Pipewire

My Pulseaudio configuration

When we have

load-module module-alsa-sink device=hw:PCH,0 sink_name=line_output
load-module module-alsa-source device=hw:PCH,0 source_name=microphone_input
load-module module-alsa-source device=hw:PCH,2 source_name=line_input

#.ifexists module-udev-detect.so
#load-module module-udev-detect
#.else
### Use the static hardware detection module (for systems that lack udev support)
#load-module module-detect
#.endif

on /etc/pulse/default.pa (or ~/.config/pulse/default.pa) It tells us that:

  • There is a sink on hw:PCH,0
  • There are 2 sources on hw:PCH,0 and hwPCH,2
  • Automatic detection is disabled

How I did on Pipewire

On Pipewire the settings are located on /etc/pipewire, so you can copy them to ~/.config/pipewire/ to set your own, just like Pulseaudio.

So, to make something like that on Pipewire we should disable auto-detection on media-session.d/media-session.conf at probably line 90 by commenting alsa-monitor:

        #alsa-monitor

And to manually set what sources and sinks we edit pipewire.conf like this:

pipewire.conf 
context.objects = {
    adapter = {
        args = {
            factory.name    = api.alsa.pcm.sink            # The ALSA sinks object on Pipewire
            node.name       = line_output            # A name for the device
            node.description        = "Line Output"            # A visible name for the device in the tray (mandatory quotes)
            media.class             = Audio/Sink            # Another sink parameter on Pipewire
            api.alsa.path           = "hw:PCH,0"            # Finally the sink location. Quotes are mandatory.
        }
    }
    adapter = {
        args = {
            factory.name    = api.alsa.pcm.source            # Here we did the same thing, just change "sink" to "source" and the names.
            node.name       = microphone_input
            node.description        = "Microphone Input"
            media.class             = Audio/Source
            api.alsa.path           = "hw:PCH,0"
        }
    }
    adapter = {
        args = {
            factory.name    = api.alsa.pcm.source
            node.name       = line_input
            node.description        = "Line Input"
            media.class             = Audio/Source
            api.alsa.path           = "hw:PCH,2"
        }
    }
}

Then you should probably get the devices like I asked on this article.

Basically there is no correct way to do this. I think the idea is to adapt what you need to Pipewire. My adaptations are completely compatible, so I had no problems (basically It was a pipewire object instead of a pactl module).
