Sorry, but no one else is talking about headphones. Specifically the jack. I had been using my C3000 as an mp3 player, but now I only receive one channel, unless I push the plug to one side. I've seen this before in small radios. It's likely the jack is bent near where it connects to the board.
I have yet to take my Z apart, but my experience has been dismal trying to repair these things. Any hints or tricks? I don't want to risk getting no sound at all, but I would also like to get VOIP working, and not have to carry around a separate gadget to listen to podcasts.
