Using tv as media player for door bell take to much time

Hello,
All is in the title. I have the functionality, but there is to much time to play the song.

I use recent Sony TV as media player, but person that push the door bell buton can go away before I heard the song.

Can you explain the reason of the delay, can it be shorter ? What smart media player can I use to if it is not possible to reduce the latency time.

Many thanks to help me !

Best regards

Thierry
