Created virtual device on PipeWire to play sound through 2 bluetooth devices at the same time, it worked but after restarted I have no audio anywhere. Help?

[greatdong3000@lemm.ee]

So I wanted to watch a movie with another person and we both using our own bluetooth earbuds. So I found this code to be placed inside context.modules in the PipeWire config file:

{   name = libpipewire-module-combine-stream
    args = {
        combine.mode = sink
        node.name = "bt-broadcast"
        node.description = "A combined sink to all bluetooth devices"
        combine.latency-compensate = false
        combine.props = {
            audio.position = [ FL FR ]
        }
        stream.props = {
        }
        stream.rules = [
            {
                matches = [
                    # any of the items in matches needs to match, if one does,
                    # actions are emitted.
                    {
                        # all keys must match the value. ! negates. ~ starts regex.
                        # matches all bluez sinks
                        node.name = "~bluez_output.*"
                        media.class = "Audio/Sink"
                    }
                ]
                actions = {
                    create-stream = {
                        combine.audio.position = [ FL FR ]
                        audio.position = [ FL FR ]
                    }
                }
            }
        ]
    }
}

I am using Debian 12 stable so the PipeWire config file was the one at /usr/share/pipewire

I did that, then systemctl restart wireplumber and maybe restarted some other services don't remember. It worked.

We watched the movie, I turned off the laptop. Now I picked it up again and there is no sound at all, whatever output device I choose on the Gnome config UI or on the EasyEffects UI, I can't get sound on the built in speakers, can't get on the bluetooth earbuds either (selecting the virtual device or the actual single earbud).

Help?

Need the status of the levels on the individual outputs. These may be selected as the primary output right now. Try disabling this config and restart.

Next steps are checking mixers to make sure your levels are set for the intended output (sometimes they get auto-muted when switching output devices).

in the future if you want to do this again qpwgraph might be a easier way to do it

if you install qpwgraph, what connections do you see? a screenshot may be helpful
