No upmix 5.1 pipewire after config [solved]

[Bedson]

Hi,
fresh install plasma desktop. After installation and configuration change (client, client-rc and pipewire-pulse) no upmix to 5.1. Several versions previously worked without a problem. I tried changing the configuration in both .config and /usr/share/pipewire (no configs in /etc/pipewire) - no effect.
configs:

stream.properties = {
#node.latency = 1024/48000
#node.autoconnect = true
#resample.quality = 4
#channelmix.normalize = false
channelmix.mix-lfe = true
channelmix.upmix = true
#channelmix.upmix-method = psd # none, simple
channelmix.lfe-cutoff = 140
#channelmix.fc-cutoff = 12000
#channelmix.rear-delay = 12.0
#channelmix.stereo-widen = 0.0
#channelmix.hilbert-taps = 0
#dither.noise = 0
}

Speakertest -c 5.1 works fine. In plasma desktop set to 5.1 and in the test all speakers work.

In the 0.3.68 release note :::
Upmixing was disabled again by default. We now ship config files that
distros can install to enable upmixing again. (#3081)

There is a file ‘20-upmix.conf’ in the four directories with content like the following:
/usr/share/client.conf.avail/
/usr/share/client-rt.conf.avail/
/usr/share/pipewire.conf.avail/
/usr/share/pipewire-pulse.conf.avail/

Enables upmixing

stream.properties = {
channelmix.upmix = true
channelmix.upmix-method = psd # none, simple
channelmix.lfe-cutoff = 150
channelmix.fc-cutoff = 12000
channelmix.rear-delay = 12.0
}

I guess you can just insert to pipewire-pulse.conf.
You can also copy to ~/.config/pipewire/pipewire.conf.avail/20-upmix.conf and see if it is loaded automatically.

Thx! I overlooked those “avail” folders. After the indicated modifications, it started.
