Microphone input not recognised as a response


I have a problem using voice key with a built-in microphone on a Mac.
The voice key is not triggered at all while my experiment is run.

On the microphone input screen under the participant input tub shows the sound is detected, so the blue indicator goes up and down on the bar, but the image of a microphone never appears on the photo below, which indicates that it is not being recognised as a response.

This problem is absent when the experiment is run on the version 4.5.

Can anyone help, please?

In SuperLab 5.0.0, there is a user interface glitch where the microphone photo does not appear in that window. This has been fixed in 5.0.1. The experiment should run equally well in 5.0.0 and 5.0.1. The only difference is the repaired test photo of the microphone.
