I don't think it is a solution even, this just seems to close the sound device again if it's idle. The problem still persists, because it will still consume those CPU cycles while in a call (on top of the echo cancellation that is). I did some tests with PortAudio directly, see http://techweb.rfa.org/pipermail/portaudio/2008-October/ 008943.html for the relevant thread. The issue wasn't really solved. Ruud Klaver AG Projects
