iPhone 5 Ear speaker no sound

The speaker up top (The one right under the camera) is no longer working. Speakers on the bottom works fine, so I can talk using speakers. If I plug in my headset, it also works.

What I have tried so far:

Reset iPhone, both ways (power button, and power + home button)

Reset iPhone as a new phone

Clean the speaker

Clean headphone jack

Checked the sound setting

Checked the toggle above the volume button

Plug and unplug headset numerous times

Running out of ideas, thanks in advance
