Touchscreen Audio Feedback?

I received a really nice touchscreen from InTouch Screens in Australia just today. The exact model that I have is the INDT215.
It worked right out of the box, no calibration or anything. I am using the ProbeBasic screenset which incorporates some nice large buttons.

What I now want to do is to have some audio feedback when the touchscreen is pressed (i.e. a short 'beep' with every mouse click).

Has anybody been able to achieve this and how?

Maybe a hint here?

Thanks for the suggestion @andypugh.

Actually I did try installing the Elo driver to check it, however it wasn‘t compatible with my touchscreen.

I was referring to "beep on touch" in the "control panel applet"

Though that might be a feature only in the ELO driver.

I can configure different buttons/operations to make different beeps in my axis.tcl file if u wish.
herewith example axis touchscreen.
