Can I get some help fixing a Nexus 4 no sound output from speaker, ear piece or jack

[Deep Saur]

My nexus 4 fall from height, after that device stopped producing sound from all outputs.
Neither of speaker, ear piece or jack is producing sound. The only way to get audio output is external independent device like bluetooth hands-free or bluetooth speaker.
The LG service center couldn't get the exact point of problem , just asked to replace the motherbord, which is very expensive. Looking for any help. If the problem is in mother board can any one let me know low to fix sound hardware control in nexus 4 motherboard.

Hi there Saur!

I"m afraid that its going to be difficult for us to troubleshoot the issue, without having the actual phone to look at, especially if LG couldn't locate the problem. I would suggest locating a Tear-Down video, which should exist, and see if you can locate on the mother board, where the sound hardware is located, and maybe something just came unplugged, to which I have seen happen.

Good Luck, keep us posted!
