New audiobook distorted on old iPod
Just bought a new audiobook from iTunes store: Golden Prey by John Sanford. Plays okay on computer. Voice is very distorted on my ancient iPod. All other audiobooks that I have sound fine on iPod (even ones which just came out several months ago). This audiobook was just released last week.
Any ideas? Have audiobook file types upgraded to the point where I'll have to buy a new iPod to listen to new audiobooks?
