< I forgot to mention that the audio signal IS SHOWING up when you tap the mike or speak, but nothing comes out of the speakers or headphones >

< Could it be a software glitch, or a connection issue in the rear? >

The audio signal coming from the microphone through the cable into the pre-amp is an analog audio signal and not digital which indicates your issue is very likely a software glitch, setting or internal physical fault. If your meters are showing a mic signal, it's there and being muted somewhere further along the signal path.

The fact of the audio showing in the meters but no sound also eliminates the external cable connection because the signal is passing through to the pre-amp and the meter taps the pre-amp signal. A connection issue could cause distortion or intermittent cut-outs or complete failure of the signal path.

Because the problem is intermittent and occurs randomly, the issue sounds like it's a physical connection fault on the internal pre-amp board of your Tyros 5 keyboard called a cold solder joint. It's a very common fault that is a simple fix of locating and re-soldering the offending connection. The issue is the keyboard has to be opened up and possibly taken partially apart to access the PC board.
