<p>
The property probe is a way to autodetect allowed values for a GObject
property. It's primary use is to autodetect device-names in several elements.
</p>
<p>
The interface is implemented by many hardware sources and sinks.

Checks whether a property needs a probe. This might be because
the property wasn't initialized before, or because host setup
changed. This might be, for example, because a new device was
added, and thus device probing needs to be refreshed to display
the new device.
