1 year ago until i noticed that any audio processed with easyeffects has a latency grater than 5ms .
This is the latency that the audio application is requesting to the audio server. PipeWire is free to use it or not. What it is going to do depends on the situation.
it seems like 5ms is the lowest value and easyeffects is unable to find the correct latency so it sets it to the lowest.
EasyEffects does not try to set any latency. As the game is requesting a low latency PipeWire is switching to it. By default it tries to please the client requesting the lower latency.
You can have a better idea about what Pipewire is doing running pw-top. But based on my experience whenever games are running too low quantum sizes (latency) are used. Your EasyEffects logs is showing quantum sizes as low as 256. For some apps this is fine but with games I almost always hear a crackling.
When I am playing I usually launch the game with the environmental variable PULSE_LATENCY_MSEC set to something reasonable so that the game does not force PipeWire to use a too low latency.

Describe the bug
i have seen audio cracking issue #1058 which is similar to what i have except that my issue is with some steam games.

no audio cracking , easyeffects sets the correct latency

Additional Information
after a heavy researches i have noticed the the following :
when govnor is sat to power saving and under load >25 the audio cracking appears ( not every time ), but when i change govnor to performance the cracking disappears. so, i tried to set both easyeffects and pipewire to the highest priority but got minor improvement . i also changed maximum buffer size to 64 but no luck.
i have disabled all plugins and ran audio on easyeffects , but the audio is still cracking despite that it has no modifications to do on audio. ( literally no change in cracking )
until i noticed that any audio processed with easyeffects has a latency grater than 5ms .
here is audacious as an example
also, this is a game ( open GL ) running from steam
but when i run a game with cracking i get i 5ms only ( as shown below )
which is to quick for my cpu to handel unless i change govnor to performance
despite easyeffects taking 15% of the cpu
it seems like 5ms is the lowest value and easyeffects is unable to find the correct latency so it sets it to the lowest. i am running xwayland as compositor which might have something to do with this issue . also, i am setting frame limit to 30fps via goverlay ,but i dont thing that has relation to the issue .
the easiest fix is to somehow manually adjust latency
thank you for your hard work in advance
