No sound during call

Hello guys! Recently my iPhone started behaving strange. When I try to call someone from contacts the phone stays in contacts, but actually calls in the same time. Also when someone calls me i can’t hear them and they can’t hear me. In all other circumstances the mic and the speaker are ok. What may be causing the problem?

I tried with a different antenna, but it didn’t solve the problem. Thank you in advance!

Dan

Can you hear them when you switch to loudspeaker?

No, I hear no sound on loudspeaker. Even with headphones, except the clicking sound of inserting the headphones into the headphone jack. I am not an expert but I think it is some sort of Audio IC issue.

Sure could be an Audio ic issue, in which case it's not worth fixing

@pomikoli i second this, definitely audio IC not worth fixing unless you know SMD and the phone has sentimental value.

@dan2002 Have you ever tried with a earphone, is that working?
