Create more dsp and mixer devices

[User Gandalf]

 Hello,

The gaim instant messenger has support for three sound devices: ESD, 
Arts and using a command. I'm not sure what 'ESD' means. Is it the 
'esound' package? (Enlightment sound daemon.) Somewhere I read that 
FreeBSD can do the same (e.g. sharing one audio device to multiple 
programs). Can you point me to a documentation where I can read more 
about this? I would like to know if it is worth to install esound. What 
other options do I have if I want to use gaim with sounds?

Thanks,

   Les
