Right ear stereo doesn't work

[Boni__]

Ok so i did this test https/www.youtube.com/watch?v=ZjAQylVPU3I
I can hear Left on Both sides (it sould be only on left side but i can hear it on right side too)
I cant hear right,its silent
Both i can hear,well both

What the hell is the problem here i watch any video normal but these test seem to show its not!

Good lord, this shouldn't be that hard.

I wager you did not plug the cable ALL THE WAY IN.
