Re: No sound with ladspa plugin in newer alsa versions

[Steve deRosier <derosier@pianodisc.com>]

Jaroslav, thanks for replying.  I'm not 100% sure that my setup is right 
(it was quoted in the origional email), but since it used to work with 
these setings, but now doesn't...?...

I've looked over both the setup in my asound.conf and the output from 
the verbose mode aplay and I have nearly the same stuff as you show.

Here's the setup out of my /etc/asound.conf file:
# cat /etc/asound.conf
pcm.pd
{
    type ladspa
    slave.pcm "plughw:0,0"
    path "/lib/ladspa"
    plugins
    [
       {
          label amPitchshift
          input
          {
             controls [ 0.890899 3 ]
          }
       }
    ]
}

And the aplay output:
# aplay -v -D plug:pd alla_luce.wav
aplay: /lib/libasound.so.2: no version information available (required 
by aplay)
