[LAU] LADSPA Plugins from ALSA,would like some help, please !

Hello, Im trying to implement a kind of MAXXBASS plugin on an headless machine (running in mono). If it works, I would be happy to share it if someone is interrested. However, to do so I need some help to better understand the LADSPA syntax. Here are two example that I would like to implement : *#1* root@SheBe:~# analyseplugin tap_tubewarmth.so Plugin Name: "TAP TubeWarmth" Plugin Label: "tap_tubewarmth" Plugin Unique ID: 2158 Maker: "Tom Szilagyi" Copyright: "GPL" Must Run Real-Time: No Has activate() Function: No Has deactivate() Function: No Has run_adding() Function: Yes Environment: Normal or Hard Real-Time Ports: "Drive" input, control, 0.1 to 10, default 2.575 "Tape--Tube Blend" input, control, -10 to 10, default 10 "Input" input, audio "Output" output, audio *And my asound.conf is :* pcm.WarmTube { type ladspa slave.pcm "plughw:0,0"; path "/usr/lib/ladspa" channels 2 plugins { 0 { id 2158 policy none input.bindings.0 "Input"; output.bindings.0 "Output"; input { controls [ 2.575 10 ] } 1 { id 2158 policy none input.bindings.1 "Input"; output.bindings.1 "Output"; input { controls [ 2.575 10 ] } } } } That produce the following Error : /root@SheBe:~# squeezelite -a 80:4:16:1 [21:58:35.206794] test_open:130 hwparam init error: Invalid argument [21:58:35.208477] output_init_common:373 unable to open output device/ *#2* root@SheBe:~# analyseplugin harmonic_gen_1220.so Plugin Name: "Harmonic generator" Plugin Label: "harmonicGen" Plugin Unique ID: 1220 Maker: "Steve Harris <steve(a)plugin.org.uk>" Copyright: "GPL" Must Run Real-Time: No Has activate() Function: Yes Has deactivate() Function: No Has run_adding() Function: Yes Environment: Normal or Hard Real-Time Ports: "Fundamental magnitude" input, control, -1 to 1, default 1 "2nd harmonic magnitude" input, control, -1 to 1, default 0 "3rd harmonic magnitude" input, control, -1 to 1, default 0 "4th harmonic magnitude" input, control, -1 to 1, default 0 "5th harmonic magnitude" input, control, -1 to 1, default 0 "6th harmonic magnitude" input, control, -1 to 1, default 0 "7th harmonic magnitude" input, control, -1 to 1, default 0 "8th harmonic magnitude" input, control, -1 to 1, default 0 "9th harmonic magnitude" input, control, -1 to 1, default 0 "10th harmonic magnitude" input, control, -1 to 1, default 0 "Input" input, audio, -1 to 1 "Output" output, audio, -1 to 1 *And my asound.conf is :* pcm.overtone { type ladspa slave.pcm "plughw:0,0"; path "/usr/lib/ladspa" channels 2 plugins { 0 { id 1220 # Overtone (Harmonic Generator) policy none # Apply Overtone to channel 0 input.bindings.1 "Input"; output.bindings.1 "Output"; input { controls [ 0 1 1 1 1 1 1 1 1 1 ] } } 1 { id 1220 # Overtone (Harmonic Generator) policy none # Apply Overtone to channel 1 input.bindings.1 "Input"; output.bindings.1 "Output"; input { controls [ 0 1 1 1 1 1 1 1 1 1 ] } } } } That produce the same Error : /root@SheBe:~# squeezelite -a 80:4:16:1 [21:58:35.206794] test_open:130 hwparam init error: Invalid argument [21:58:35.208477] output_init_common:373 unable to open output device/ Note that I don't need control, although I can make it work from the regular way with the pluequal and control Equal, but here, I want/need to implement it directly from within my asound.conf Thank you for your help !
