iPhone 5 external speaker stopped working...

was on a call on speakerphone & the external speaker stopped working.

later i watched a youtube video and half way in it stopped working again.

tapped the back on the phone & it went in & out.

now its just completely out.

to be fair my iPhone screen is broke from a drop about a month ago. but the speakers worked 100% since today.

i've had it a year so I think I'm over the 1 year warranty.

am i completely out of luck?

i can't see them fixing the speaker when i take it in with a broken screen…

help !!
