Headphones and speakers playing in tandem - SOLVED

Hey everyone, I can gladly say that I have my mintypi working in nearly all aspects. The buttons all work, the speaker works, the screen is working, but I have a problem that I can't seem to figure out. When I plug in headphones, the sound comes from both the headphones and the speaker. Does anyone know what might be causing this and how to fix it? It isn't super essential but I would like to use the headphone jack if possible. Thanks.

P.S. I'm also having trouble finding how to display the battery monitor. If anyone could point me in the right direction it would be appreciated.

Did you solder the no headphone jumper? It's 2 tiny solder pads with a headphone symbol near it? If so remove that bridge.

The Mode button will show you the battery level once you press it UNLESS you did not solder SCL and SDA properly.

I did not solder the headphone skip pads, as I knew I'd want a headphone jack.

Can we see a picture of your soldering please? Both front and back of the controller board.

I think there might be some solder somewhere that got into the headphone jack from the legs. Be sure to get some good pictures of the headphone socket from all angles so we can see.

Hi everyone, I apologize for the delay, I've been busy these past two days, but in that time the problem fixed itself, then made the speaker stop working after more use of the headphone jack, and then all sound stopped entirely upon further use in attempts to reverse the effect without needing to disassemble. The headphone jack's, soldering looks like this. Thanks for all of your help.

Yeah that is a lot of solder. As Helder said, some may have gotten inside the headphone jack itself. Do you have some solder wick that you can use to try and soak up some of that solder? And can you look down the barrel of the headphone jack and see if there is any solder inside of it?

I do not have solder wick, but I do have a solder sucker. Could that help, or should I order some wick?

Edit: It does look like there is some solder inside the jack, do I need to do anything special to get it out, or just work at removing solder?

Just work on removing the solder. Solder wick would be best but a sucker could work if you angle it right.

Thanks. I did that and it seemed to work, so I reassembled the thing only to have the speaker stop working again, so more solder must still be in the jack. Unfortunately trying to open it back up a screw got stuck in the threads and I can not get it out without destroying the face plate or the tin. So as unfortunate as it may be, the system may be stuck as a headphones only device if I want sound. Thanks for all the help though, if I hadn't screwed myself over, I'm sure it would have worked.
