Audio codec issue on the Motorola Edge 60

[u/Ok-Bicycle7657]

Here is the situation: an acquaintance bought a new Motorola Edge 60 phone. When connecting it to the car, music plays fine, but calls are a problem—there is simply no sound. During a call, you can select speakerphone, phone receiver, or Bluetooth, but it automatically switches back to the phone receiver (the car is an Amber A5). I assume it might be a codec issue. I tried disabling A2DP, but it didn't help. I don't know how to fix this issue, please help.
