Earpiece dead

After replacing my touch screen on my 9900 my earpiece is dead. all functions were fine before the replacement and all functions save the earpiece are fine after the replacement. No adjustments to software have been been made etc etc. Is the earpiece a pressure fit i.e. could the connection have come loose during the repair? The screen replacement went pretty much without incident so i was surprised to see this issue pop up. Thanx!

Sound like you need to go back in & make sure all is connected.

problem solved.... no idea why or for how long but solved non the less. it just started working again for some reason. Anyway, thanx for the input and hopefully that is the end of the issue.
