The speakers on my 3DS work perfectly fine on their own, but when I try to use my headphones to listen to the sound, it only works in the right ear. The only way it will work in both ears is if i push down on the headphone input cable thing.
This happens on every 3DS sound setting (Surround, stereo, & mono) and all 100% functioning headphones I've tried.
Is this problem able to be solved by just cleaning inside of the jack with a cotton swab + alcohol or does it need some kind professional repair?
