All audio has stopped working

First it has started with the loudspeaker not being functional but the top speaker was still loud. After a while I could not call people and use USSD codes at all. Eventually the top speaker got soft and all audio stopped working. I can’t even make a WhatsApp call because it just says call failed. I am suspecting that it is something to do with the audio ic or something along those lines. If anyone has any suggestions it would help

Thank you in advance
