[Alsa-user] LADSPA endeavour : Unable to load plugin

[Elie M. <lac...@wa...>]

Hi people,

I'm attempting to setup an equalizer at ALSA level, and the tap_eq LADSPA p=
lugin seems to be the right way to do this. However I found only very few d=
ocumentation on LADSPA plugins usage in ALSA.. it was still enough to fill =
my asound.conf file :

######
defaults.pcm.rate_converter "samplerate"

pcm.hd595_ladspa {
    type ladspa
    slave.pcm "plughw:0,0";
    playback_plugins [ {
        id 2141
        label tap_eq
        filename "/usr/lib/ladspa/tap_eq.so"
        input {
            controls [ 60 -4.5
                       170 0
                       310 -4.5
                       600 -11
                       1000 -8.5
                       3000 -13
                       12000 -15
                       14000 -8.2 ]
        }
    } ]
}

pcm.hd595 {
    type plug
    slave.pcm "hd595_ladspa";
}
######

thought it doesn't work for now. Here's the aplay output :

$ aplay -Dhd595 test.wav
ALSA lib pcm_ladspa.c:1481:(snd_pcm_ladspa_add_plugin) Unable to load plugi=
n 'tap_eq' ID 2141, filename '/usr/lib/ladspa/tap_eq.so'
aplay: main:550: audio open error: Aucun fichier ou r=E9pertoire de ce type

/usr/lib/ladspa/tap_eq.so is present, also commenting some of the id/label/=
filename lines doesn't help either. .
Something wrong with my config ? ( ALSA 1.0.13 drivers and lib )

Cheers!=20
