playing a sound on message arrival

[rudi48]

Hello Christoph, is it possible to play a sound on arrival of a message?
That is useful in order to control a door or window. See my web page about it:

For Android I have such an App: MQTT Snooper, see the screen shot:

If you tap on the bell symbol, the bar below switches from white (OFF) to red (ON).
The button to the right on the bell signals Subscription OFF/ON. It toggles, when you tap on it.
In a different mask you select a system sound for the bell.
Regards, Rudolf

This doesn't sound (hah!) very useful to me as MQTTinspector has to be in the foreground anyway. ..
