I've just started looking at ALSA, and I have a couple questions that
I hope will be pretty easy to answer.
I'd like to log stream creation as streams are brought up and shut
down. Should I use an I/O plugin for this? Is there code I should
start to look at for doing this. Ideally I'd like to get a
notification once streaming starts on a PCM and when it stops.
If I wanted to manipulate DMIX settings in response to streams being
started and stopped, is it best to do this via a plugin (possibly the
same one that I'd write for the stream monitoring, or from an external
app that has a connection to the monitoring plug).
Finally is it possible to change the physical ALSA sink for a running
PCM (for example if I have two devices, I start streaming on the first
and decide in response to a user even that I need to stream to another
