Hi John,
Can you try a few things:
First just reinstall it, in case it has lost permissions to capture the audio:

When Jaksta Screen Recorder is recording, make sure you turn the volume up high.
When you play back the recorded video afterwards, turn its volume up high. It's possible the sound is very quiet.
Any luck?
Thanks,
Ben
