pipewire loopback devices break osu

[linux-leo]

putting the following under ~/.config/pipewire/pipewire.conf.d/swap.conf breaks osu:

context.modules = [
    {   name = libpipewire-module-loopback
        args = {
            audio.position = [ FL FR ]
            capture.props = {
                media.class = Audio/Sink
                node.name = swapped
                node.description = "swapped"
                #node.latency = 1024/48000
                #audio.rate = 44100
                #audio.channels = 2
                #audio.position = [ FL FR ]
            }
            playback.props = {
                #media.class = Audio/Source
                node.name = swapped
                node.description = "swapped"
                #node.latency = 1024/48000
                #audio.rate = 44100
                #audio.channels = 2
                audio.position = [ FR FL ]
            }
        }
    }
]

I wanted to use this to swap the left and right sides of my speakers as they appear to be wired incorrectly. But I can't play osu this way, the speed at which the game runs at startup is too high.
