Pipewire upmixing 2.0 to 5.1

Hello,

I want to activate upmixing 2.0 to 5.1 in pipewire.

I create 20-upmix.conf in /etc/pipewire/pipewire-pulse.conf.d and write this in it:

stream.properties = {
    channelmix.upmix = true
    channelmix.upmix-method = psd #simple or psd
    channelmix.lfe-cutoff = 150
    channelmix.fc-cutoff = 12000
    channelmix.rear-delay = 12.0
}

And I restart with:

systemctl --user restart pipewire

But no change !

Thank’s for your help

It works, need te reboot I assume :upside_down_face:
