setLocalEcho(true) only works if microphone is not muted

[JulianGro]

When pressing the "Test your voice" button in the audio settings, while being muted in said audio settings, your voice doesn't get repeated to you. It uses AudioScriptingInterface.setLocalEcho(true), which I assume is on the C++ side.

Apparently, this is a bug, since the API documentation specifically says that both mute and push-to-talk should be ignored: https://apidocs.overte.org/Audio.html#.setLocalEcho
