Duplicated streams

Hello

I'm on Arch with Kde Plasma and every app that plays audio generates two duplicated audio streams, here is the output from Helvum:

I have a spare laptop with the same installation, Arch and KDE Plasma and I don't have either of these problems... Can anybody help please?

Thanks

Re: Duplicated streams

First try clearing it's cache & restart, also ensure the Profile is set to smtg like Analog Stereo Output rather than Pro audio, && if you have leftover configuration from pulseaudio (like combined-sink or module-echo-cancel) in your user config, pipewire might be creating a virtual "echo" of every stream? `pactl list modules`

Re: Duplicated streams

Don#t bump-
Random screenshot fragments tell little about what's going on - this could even be a bug in the GUI thing you're looking at and you're also hiding the destination.

Compare

wpctl status

between the systems.
