My 30 gig ipod video has recently lost sound with both mp3s and videos It all used to work before... It will play and the time will tick but no sound comes out. Its not the headphones or the headphone jack because it doesn't work on my fm transmitter either and that plugs in through the bottom. I've done the 5 rs and everything... Could it be the firmware? I got the latest 1.2 something or other.... Should I downgrade? If so how? What else can I try? Thanks in advance guys.
