Sound not audible

this is what you will do, when you sync it again stop the automatic sync the click on your player on the itunes window to see its details, you will see 3 or 4 checkboxes and check manually add music or songs and ucncheck if there is any, the box that says automatically sync music, then click sync, it will start syncing again the disconnect. add songs only to the folder where itunes have got the songs so that next time you sync the ipod the songs previously added wont be erased.

Green and orange?? Sounds like you need to restore your iPod.
Understand this: iTunes plays what is on the computer, NOT the iPod.

you **** his ***** then he will be happy

Try resynching your IPOD with Itunes on your computer then try to play again. If that does not work please respond and we can try another option. Also after you synch try the update option on Itunes as well that could fix any problems on the sofware side of your IPOD.

You need to reset your ipod. Flip the hold switch on then off, then press select button and menu button at same time. Hold for 10 seconds or so. Ipod should shut off and reboot to apple screen. If this doesn't work first time try again. This should solve any stuck screen problems. Mine was stuck on pioneer screen and this operation fixed it.

It droped once (it wasnt a serious drop) a month ago. After that drop it worked well. Problem occured after last sync a week ago.

A restore might solve the problem.

Make sure your headphones are working properly by testing with your computer headphone jack.

Is the headphone port on the Nano loose?

Connect the Nano to your iPod dock and see if you can head audio through the docks headphone jack.

If the headphones work, and you can get audio out of the dock headphone port, then there is a problem with your Nanos headphone jack.
