I'm having problems with the ear-speaker of my HTC Hero. It has been working great for near 4 months now then out of nowhere the ear-speaker stopped working yesterday. Whenever I try to make or receive a call I cannot hear the other person speaking. If I switch to speaker or headset then I can hear them just fine, but if I try to use the ear-speaker there's nothing. Anyone got any bright ideas on what's wrong/how to fix it? I have the newest firmware (2.73) and it's not rooted or anything else.
