[SOLVED] configuring parametric equalizaton in PipeWire

I have followed the section on parametric eq here: https://wiki.archlinux.org/title/PipeWi … ualization

but I am stuck on

select "Equalizer Sink" as your default sound output device

I do not know what exactly this means, and I have been unable to glean any information about what to do from the PipeWire wiki page, and googling has proved unfruitful.

I would guess that it would be a sink, due to the name "Equalizer Sink", but listing sinks with pactl doesn't show any sink named "Equalizer Sink"

>pactl list short sinks
0       alsa_output.pci-0000_08_00.6.analog-stereo      module-alsa-card.c      s16le 2ch 44100Hz       IDLE

and listing cards with pactl also doesn't show any equalizer devices

>pactl list short cards
0       alsa_card.pci-0000_08_00.1      module-alsa-card.c
1       alsa_card.pci-0000_08_00.6      module-alsa-card.c

I was able to find an Equalizer Sink using qpwgraph:

but I don't know if this helps because the Equalizer Sink block persists if I remove the equalizer config files.

Re: [SOLVED] configuring parametric equalizaton in PipeWire

sudo fuser -v /dev/snd/*
systemctl --user status pipewire{,-pulse} pulseaudio wireplumber
pactl info

I'm suspecting your pulse is not actually running on pipewire, install pipewire-pulse and replace pulseaudio with it.

You were 100% percent correct on that.

>sudo fuser -v /dev/snd/*

                     USER        PID ACCESS COMMAND
/dev/snd/controlC0:  SirBlobfis    922 F.... wireplumber
                     SirBlobfis   1187 F.... pulseaudio
/dev/snd/controlC1:  SirBlobfis   1187 F.... pulseaudio
/dev/snd/pcmC1D0c:   SirBlobfis   1187 F...m pulseaudio
/dev/snd/pcmC1D0p:   SirBlobfis   1187 F...m pulseaudio
/dev/snd/seq:        SirBlobfis    915 F.... pipewire

The first line of this output really hammers that home

 >systemctl --user status pipewire{,-pulse} pulseaudio wireplumber

After installing pipewire-pulse and removing pulseaudio:

and Equalizer Sink appears as a Playback Device in system settings.
Thanks.
Solved.
