Unhappy [Q] Volume coming from speakers but only most sounds go to AUX slot.

Long story short , my S3 was detecting only one of my headphones, I read somewhere on a forum that if this happened you need to put a piece of tin foil in the aux slot and I did just that and it worked. - sound in both headphones. but now there's no sound coming from the speakers. I mean no media sound. if someone calls me I hear the phone ringing but I must put it on speaker to actually be able to hear the person.

here's a video I just shot of what I mean.

any solutions? I removed the screws to hopefully get the aux slot out and clean it up but I don't really know how to remove it and I don't wanna break anything.

help? please!
