SOS: iPod and speaker dilemma. HELP!

My ipod worked well with my speakers until IOS 4.0, i think that that is the problem, now i doesn't work and i have it updated until version 4.1? is that the problem?, i even bought some panasonic new speaker "made for ipod" and they say that they support my ipod touch 2G. The speakers are fine because i have tried them with other ipods right now.

PLZ HELP, MAYBE IF I RESTORE SOMETHING IT WORKS?

Can you hear your stuff through ear phones/buds?

Forget it, i just restored it and worked, i think that maybe it was just a software issue...
