Question FM Radio stopped working

One day it works and the next nothing.
Picks up the channels but no sound at all can be heard.
Using Stock 4.4.4, rooted and xposed module.

Tried a couple of sets of head phones and no difference.
Also tried SpiritFM and same result. Podcasts, music all work using the same headphones, also so does the external speaker.
Is there a solution or has the chip failed?
