[SOLVED] Wireplumber filter chain

I want to try out pipewire's Dolby Pro Logic II encoding but copying the config file from it's wiki results in a failing pipewire service. Service reports this:

Jul 29 13:08:07 orakArch pipewire[1208]: default: failed to load plugin 'surround_encoder_1401': No such file or directory
Jul 29 13:08:07 orakArch pipewire[1208]: mod.filter-chain: can't load graph: No such file or directory
Jul 29 13:08:07 orakArch pipewire[1208]: pw.conf: 0x5578ad0bd100: could not load mandatory module "libpipewire-module-filter-chain": No such file or directory
Jul 29 13:08:07 orakArch pipewire[1208]: default: failed to create context: No such file or directory
Jul 29 13:08:07 orakArch systemd[756]: pipewire.service: Main process exited, code=exited, status=254/n/a

I did a bit of googling and found out this is because of the switch from pipewire-media-session to wireplumber, which apparently doesnt have these effects and plugins. Any way to get them without installing pipewire-media-session which breaks dependencies?

The plugin is not part of the session manager but a ladspa plugin you need to find where that ladspa plugin is from, the plugin in question is part of the swh-plugins package.

Solved. The problem was that the config file wasn't in ~/.config/pipewire/pipewire.conf.d/

Im not sure why that would be a problem, but moving the file to that location solved it.
