Audio doesn't work after repair

Good morning everyone,
 The car mechanic was able to get my car back on its feet after the crash. Everything apparently works with the exception of the radio which, although it works at the touch level and all the functions, can't hear anything.
I did a scan with odb eleven and this is the result. What do you think it could be?
I point out that before the intervention of the car mechanic it worked. What can I do?
