I just made a voice recording and copied it to my desktop, and it played back with no problem through both Windows Media Player and Winamp.
Its a 384kpbs, 24kz sampling rate PCM file (which is about 1/4 the kbps of the .wav files on CD, and an unconventional .wav file).
How about if you connect the Fuze, find the file in RECORD and try to play it back from the computer, same problem?
Thanks, Black Rectangle. I took your suggestion, and it worked. I can play this new file on the Fuze through the Fuze, on the Fuze through WMP, and, after uploading, on my computer.
However: The six files I recorded in an important class 10 days ago, totaling about 6 hours of time, are not working. I originally tested them on the Fuze, and they played correctly. Once I uploaded them, they would not play. Unfortunately, I deleted them from the Fuze prior to testing the uploaded copies, so those are the only ones I have now. If I download those back to the Fuze - they do not play!
These are all the expected size. So the only explanation I can think of is that some of the headers were stripped in the uploading process. But why that should happen with these files and not with the short recordings you and I have just tested is beyond me.
