Dean, thank your for showing interest in this problem!

I followed an advice from the iTunes forum at apple.com to create these
files - I ripped an audio book CD using iTunes, encoding as AAC 64 bps
stereo. This produced *.m4a files. Then I renamed these files to *.m4b
(which is the extension for protected AAC by the way). This is necessary
so that iTunes and the iPod recognizes the files as audiobooks, to get
an "bookmark" feature.

Without renaming the files from *.m4a to *.m4b they play fine on my
Squeezebox. (And yes, I made sure, the file name is correct in the
Slimserver database.)

Last minute edit: I just found a workaround for this myself. I just
edited the types.conf file and added ",m4b" just behind the m4a entry in
the line starting with the ID "mov" - now all my m4b files play fine!
Please consider incorporating this into the next release.

Alexander.

Hi Alexander,

That's what I supposed would work. I've already made the change here.
I wasn't sure if there were m4b files that were created in other ways
out there.

Look for it in tomorrow's nightly release.
