Can anyone help me, I can't find what's wrong

Could you describe the problem a little further?

maybe one of your pads isnt covering the hole properly?

Ah! I forgot to mention that your oboe may have a crack in it. Mine jumped octaves when I had a crack.

You could try boxing its ears and teaching it better manners.

How about an old reed? I find myself that old reeds are really easy to jump octaves on.
