Sansa Clip Zip - m4a
« on: October 26, 2014, 08:43:25 PM »
I cannot get audiobooks to play when in m4a format. 

I can load the book onto the Zip, but when I press Play, it immediately stops.  Please help.

Not without at very least a link to the file.

Which file?  The audiobook file is on my computer and I can't link to it.

Data File Host
MEGA
ExpireBox
...
etc. and so on.

I could spend all day listing services that allowed you to do this.

I'm not really a computer whiz, but I'll try this <a href="http://expirebox.com/download/42ef482271d1986b1db0cb1bb0f6e3fb.html">here</a>.

Well, that didn't work.

No idea why, but that mp4 stream doesn't parse.  Not sure about that, but this makes the file playable using mp4box to rebuild the stream:

mp4box -raw 1 therenaissanceman.m4a
mp4box -add therenaissanceman_track1.aac output.m4a

It was originally an m4b file, I changed the extension to m4a.  Would that explain it? 

So can it be played or not?  What must I do?

No, that shouldn't cause an issue by my understanding.

Saratoga listed the steps to repack the stream in his last response, mp4box is a command line utility (though GUI front ends exist for it, they're largely shit) which would allow you to perform this task.

Okay, um, I'm afraid I need a little more information.  As I said, I'm not a computer whiz, so what is a command line utility or a GUI?

In that case, forget I told you how to fix the AAC files.

Instead just open the files in whatever you use on the PC and convert them to MP3 at 96 kbps.  That will also fix the problem.

Sorry, didn't mean to tick you off.

I can load mp3's .  I wanted to try an m4a as it's neater to only have one file instead of a bunch of mp3's.

Okay, I'm trying here.  I'm getting this when I try to enter the lines you said to use.

'mp4box' is not recognized as an internal or external command, operable program or batch file.

You're not ticking me off I'm just recommending that you try an easier solution given what you said.
