There are many ways in which this can happen. I give you another one:
The radio volume is selected on and off by a press switch but it is overridden to on if the transmit button is selected in the comms panel. VHF 1 radio volume is off but as the panel is on transmit on VHF1 the sound from that radio can be heard. After the cleared to land the pilot presses the PA transmit button to make the "CC take you seats for landing" (or what ever AC equivalent call) then forgets to go back to VHF1 transmit. The VHF1 volume will then be off and the GA instruction can no be heard. After landing they look down and oops, realises the error. Presses VHF1 transmit again and they are back in the loop.
On the A320 the transmit and receive are separated controls. Both pilots would have VHF1 receive selected, transmitting on any other position (including PA) doesn’t change that.
