I Just replace pipewire-media-session with wireplumber , everything works as expected but I found this warning (which I would like to get rid of).

F.Y.I - Problems solved by using filter-chain format drop-in file.
I found information how to compose daisy-chain ladspa plugins to filter-chain format that works from :
https://forum.endeavouros.com/t/pipewir … sion/31661
by Echoa...Thank you very much.
For the example this is the filter-chain file dropped in ~/.config/pipewire/filter-chain.conf.d/
~/.config/pipwire/filter-chain.conf.d/whatever.conf
# Dynamic compress
# ~/.config/pipewire/filter-chain.conf.d/
context.modules = [
{ name = libpipewire-module-filter-chain
args = {
node.description = "Dynamic compression Ladspa"
media.name = "Dynamic compression Ladspa"
filter.graph = {
nodes = [
{
type = ladspa
name = comp2
plugin = /usr/lib/ladspa/sc4_1882.so
label = sc4
control = {"RMS/peak" = 0 "Attack time (ms)" = 2 "Release time (ms)" = 650 "Threshold level (dB)" = -30 "Ratio (1:n)" = 1.4 "Knee radius (dB)" = 6 "Makeup gain (dB)" = 10 }
}
{
type = ladspa
name = comp1
plugin = /usr/lib/ladspa/sc4_1882.so
label = sc4
control = { "RMS/peak" = 1 "Attack time (ms)" = 180 "Release time (ms)" = 350 "Threshold level (dB)" = -26.67 "Ratio (1:n)" = 1.4 "Knee radius (dB)" = 7 "Makeup gain (dB)" = 10 }
}
{

name = norm3
plugin = /usr/lib/ladspa/fast_lookahead_limiter_1913.so
label = fastLookaheadLimiter
control = { "Input gain (dB)" = 8 "Limit (dB)" = 0 "Release time (s)" = 0.5057 }
}
]
links = [
{ output = "comp2:Left output" input = "comp1:Left input" }
{ output = "comp2:Right output" input = "comp1:Right input" }

]
inputs = [ "comp2:Left input" "comp2:Right input" ]
outputs = [ "norm3:Output 1" "norm3:Output 2" ]
}

"latency" output, controlYou can test the filter-chain config file by running
$ pipewire -c filter-chain.confafter execute the above command , it should be in wait-state , not begin new prompt line until you decide to terminate it by Ctrl+c. On the other hand if something wrong with the filter-chain file, after execute the command , new prompt line will appear instead of the wait-stae and without any error messages.
Your could review the by running command:
$ pipewire -c ~/.config/pipewire/filter-chain.conf.d/whatever.confThe output:
[E][04111.333744] pw.core | [ core.c: 382 core_new()] 0x5597bcf05c50: can't find protocol 'PipeWire:Protocol:Native': Operation not supported

[E][04111.334097] default | [ pipewire.c: 125 main()] failed to create context: Operation not supportedany errors beside the above example (which I have no clue about them...stupid me!) could be told what's wrong in your new created filter-chain config file .
After all experiment - if it works, you can put the command
{ path = "/usr/bin/pipewire" args = "-c filter-chain.conf" } under context.exec[.......
....] section either in pipewire or pipewire-pulse config file
Thanks for reading , anyone should have any advices to improve my config file will be highly appreciate.
