ok paul i had another look at the driver playback/capture tutorials. I have one question.Do applications initialize and use a pcm_handle of the alsa driver when they begin interaction with it?Surely not....
I thought that the driver would work totally independently of my VoIP and this is why I asked the question is it possible to change driver parameters directly.
