Audible callouts not working sometimes A320.. ils working

Hi,
Not sure if I am doing something wrong or checking in the wrong place, but I seem to have lost the audible callouts on landing in the A320 (1000, 500,400,300,200,100, 60,50,40,30, 20, 5 etc, and it is like gussing when your going to land - usually with a thud.

The first flight and landing is fine, it’s on the second flight it seems that it is not working, the ILS GS is working everytime, have the correct frequency, just puzzled on where to check next… Thanks…

The callouts can be iffy, but it has nothing to do with frequency, ILS, etc.
It is often caused, as are a few other issues, by starting a second flight - as you have mentioned.

The callouts are triggered by measurements from the radar altimeter IRL.
Watch the radar altimeter on the PFD, it will display your height.
