Stereo won't work

I'm running LMDE 6, cinnamon and i3 (trying to learn i3 still) and it's my 4th day on Linux. Today I tried to plug in my headset for the first time to see a YouTube video on i3 configuration and realized only right sound was coming out.

I tried messing with it a bit and I could get left to work with pavucontrol when I unlocked, but then right was mute. I can't get them both to work together. What is going on?

The same applies on cinnamon, I don't even know how to get left to work like I did in pavucontrol in the built in cinnamon audio thingy. I can only get the front right sounds on digital and analog stereo output.

Edit: okay I connected the headset with Bluetooth instead of 2.4g stick and it works perfectly. I'm using a Redragon Zeus if that matters. So is the problem the wireless connection? Is it not supported?
