Hi,
I think I know that problem- I have experienced the same. The
problem is that 3GP from Nokia, Sony Erricson etc embeds audio in SAMR
format (Adaptive Multi-Rate Floating point). This is a patented and
highly protected format. So, GNU/Linux playback engines like gstreamer
and xine intentionally avoid supporting it, instead choosing to
totally neglect the audio stream.

The suggested solution includes installing Real player (I don't know
if it works) or custom compiling AMR codecs. The AMR codecs are
maintained as a separate project (amrnb and amrwb libraries) at
http://www.penguin.cz/~utx/amr . I don't know how to deal with these
libraries, but hope this helps: http://flixforums.com/archive/index.php/t-240.html

Normally the audio will be AMR format. Install or update AMR plugins of your player.
This link might be useful for you.

In my experience, installing the amr packages won't make the installed
mplayer work with 3gp files. You'll perhaps need to re-compile mplayer
with AMR support enabled. I guess AMR support is not a plugin, but
compiled in to the application.
I've once used a sox command to convert a .amr audio file to wav/ogg.
The command line can be found on the internet.


regs,
