ALSA PCM plugin lifetime

[Robert Bielik <Robert.Bielik@xxxxxxxxx>]

Hi all,

 

I have a system setup where I need a post-processing ALSA PCM plugin. But how is the lifetime managed by the ALSA server? Will the plugin only be instantiated whilst there is an audio stream running?

 

Is it possible to setup an ALSA configuration that keeps the PCM plugin instantiated, whether or not there is any audio running? (there will be an external application that communicates with the plugin through unix sockets)

 

Regards

/Robert
