I tried all possible things:
path "/usr/lib/ladspa/"
path "/usr/lib32/ladspa/"
path "/usr/lib64/ladspa/"
all the same.

I am not sure, but I think there is a bug. I think I have all required deps and USE flags.

What bug? 

You need 64bit ladspa/plugins, for 64bit alsa, for 64bit mplayer. You can't mix 32bit libs/plugins there in-between.

[Comment 3 DEMAINE Benoît-Pierre, aka DoubleHP 2010-05-24 17:42:21 UTC]

Fact those drivers have not been produced by emerge ?

[Comment 4 DEMAINE Benoît-Pierre, aka DoubleHP 2010-05-24 17:46:57 UTC]

When i force
path "/usr/lib64/ladspa/"

Message becomes
[AO_ALSA] alsa-lib: pcm_ladspa.c:1502:(snd_pcm_ladspa_add_plugin) Unable
to find or load plugin 'mbeq' ID 1197, path '/usr/lib64/ladspa/'

what means, I make the change at the right place, but it has no effect ... thus ls prooving the file is absent, thus a bug because emerge should have detect i want multilib (from profile) and create the two plugins.

That could be because you haven't installed swh-plugins ? (emerge swh-plugins). I don't see what multilib has to do with any of this...

$ ls /usr/lib64/ladspa/mbeq*
/usr/lib64/ladspa/mbeq_1197.so
$ qfile /usr/lib64/ladspa/mbeq_1197.so
media-plugins/swh-plugins (/usr/lib64/ladspa/mbeq_1197.so)
