SDL-mixer and SDL-sound: Problem with mp3 support

[Vincent Prat]

Hello

Since the upgrade from squeeze to wheezy, I cannot play mp3 files with 
sdl-mixer and sdl-sound anymore.
Other audio formats (wav, ogg) work well. Is there something special to 
do to enable mp3 support or is it a bug?
By the way, the description of the libsdl-mixer1.2 package talks about 
SPMEG but in fact it has been replaced by MAD.
Thank you in advance.

Vincent
