Does Pulseaudio provide a callback mechanism or any other methods to notify application when audio device changes? I'm working on a policy application that need to know all available audio devices (speaker/mike, headphone, Bluetooth headset, HDMI) and allow user to manually set the default sink/source/port. The application need to be notified on headset/HDMI connection/disconnection. I found there is a API "context_get_sink_info_callback" that can get all available sinks' information. But rather than calling this API periodically to refresh device status, I hope PA can notify my app on the device status change. Great thanks!
