Hello,
This is my first post on the forum and I hope I was not supposed to create a new thread for this, but I'm basically facing the same issue as described here.
Some effects such as the Equalizer have no audible impact at all.
Other effects such as Crystalizer, which I would like to use, are completely grayed out and cannot be turned on.
I found some of the optional dependencies that PulseEffects has for some plugins, which are not installed by the Software Center, on a post on the Arch Linux forums. I have installed gst-plugins-good, gst-plugins-bad and gst-plugins-ugly manually, as well as mda-lv2 if I remember correctly.
I then tried rm -rf ~/.cache/gstreamer and pulseeffects -q to reset/reload things, to no avail (not even a full reboot).
I have checked for broken packages using eopkg check but everything was OK.
I'm on a fresh install of Solus 4.1 for a couple of weeks now, I must say everything apart from this has been an absolute blast 🙂
Running pulseeffects from terminal shows reveals some warnings:
