Is there any case where Sony 2500 camera can't record sound?

The problem is that we should pay special attention to this machine. Because the recording microphone uses a 3.5 jack, it is particularly easy to drop. If you are not careful, there may be no sound in the video. In order to avoid the above problems, I specially tied the audio cable plug with tape to prevent it from coming out, so that the problem of not recording can be solved.
