K, that's strange, this section isn't directly for that model but we can possibly try to trouble shoot ya
I'm about to head to work so hopefully someone else will also jump in
First let's start basic
List you device- I see you've done this
What ROM u have if any
When this issue started
You can edit the first post with the info or post it right below this one
Most likely if your using a custom ROM and plugging and unplugging a headphone didn't work I'd normally suggest a fresh install as it would be possible something didn't take during flash
Although it could also just be a ROM issue
If your on stock still would be the really unsure situation cause then it could be hardware or software failure
