[alsa-devel] Event notification

Hi,

My app needs to know about the events occurring to a sound card. Specifically, I am interested in start, stop, pause and volume change. While I could monitor volume by similar means as alsamixer does (is there any doc on this apart from the source code?), I am not sure if monitoring other events is at all possible. I would appreciate any suggestions as to how to do this.

Kind Regards, Milek
