Earpiece speaker clicks rhythmically after replacement.

Changed display+battery. Because it was broken/failling.

Accidently severed earpiece speaker.

Today arrived new earpiece.

Replaced it.

Now when i play video (youtube) theres rhythmical clicking alongside the music.

That stops few seconds after pausing the music.

Any idea how to fix it?

Update:

Inserting sim works.

But sending messages launches the tick tick tick sound.

When trying to call the called one isnt heard, only the ticking sound.

Called receives the sounds and hears me. But i don't hear them.

The code #0*# dosnt work which is mentioned below in comments.
