The effect I described seems to be due to a insufficient cpu processing power.
Infact, I've noticed that the file is played fine if I enable buffering. To do 
that I can use a mpg123 built-in command:

$ mpg123  -b  1024  song.mp3

In this case it starts playing after a initial delay, and the interruptions 
occour later with a periodicity proportional to the buffer size (1KB in the 
example).
All that is correct, because interruptions correspond to buffer full conditions.
About this, on the mpg123 web site I read:

"A recent test (GNU/Linux OS) with 0.60-beta2 showed 3% to 4% CPU usage on 
decoding high quality VBR MP3 with a pentiumII laptop with 366MHz, while a 
pentium 100MHz can easily handle two mpg123 instances in realtime (plus the 
mixing daemon that works on decoded data)"

Now, I'm wandering a 256 MHz running arm core inside the DM6441 has not 
processing power enough to do the job.
Have any idea about this issue?

Hi,
I have noticed that at high bit rates (~128 KBPS)!!!
When using VLC it plays fine, with mpg123 I get the effect you described.
BR,
