I have a audiobook that will play on my PC and will play on my wifes nano, but when I put it on my 2g touch it says its playing but there is no sound. Any ideas as to why or how to fix this? Then only thing I can think of is maybe it does not like that it is a 1.6 GB file. Most audiobooks are broken up into files about 400 MB. Is there a way to split the file into multiple smaller files?
