My question here is rather simple. How does one create a purely virtual audio device in ALSA that would be capable of:

  1. being used as an audio output destination,

  2. being used as an audio input source, outputting whatever has been sent to it.

What I'm essentially trying to achieve is outputting sound to this device, and using that device as a mic in another application (like Skype, for example), which allows me to play sounds and music in skype or whatever else that would be.

Information on this is really obscure, and search results show mostly irrelevant things, like splitting device outputs or something like that. I really have no idea where and what to look for now, so any help would be incredibly appreciated.

    Thanks, that's exactly what I wanted - though it took me some time to figure it out properly. Mar 8, 2013 at 12:21
