New subject: open ALSA device

22 May 2014

i already have a ladspa-plugin that process my audio data. this works fine
without any problems.
Due to an adaption of the functionality of my system, i want to add a
function that determines if the system works properly. This function should
send an audio signal, that is recorded afterwards. And this should also
work while no application (aplay, skype etc.) uses alsa.

Due to this I want to know if it's possible to use a plugin or an other
virtual device that "keeps the floor".

somebody of you have experience with ALSA-Devices that get never
 closed?

 I want to run a LADSPA-Plugin all the time, even if the application  above
  is not running. 
 Or float in the air if the floor below your feet is
 taken away ?

  Does sombody have an idea how to solve this
problem? 
 A plugin, by definition, needs to be plugged into something else.
 What is it supposed to do without 'the application above' ?

 If you want an alsa device which includes a plugin this can
 probably be done using an ~/.asoundrc.
