[Icecast] Start source client automatically if USB microphone is plugged in

[Dieter Knopf]

Hello,

My Linux server should automatically start streaming if someone
plugged in the USB microphone and should stop if the microphone is
plugged out again.

Is there a way to do that? Darkice stopps working without a working
audio device so I need a way to start it again.

Or is there a source client daemon available which remains online and
waits for a new audio device?

Thanks
