problems with sound :(

[Antonio Olivares]

Dear fellow testers,

I am having problems with sound again.  I try to play a simple file with mplayer and I get 

[olivares at localhost ~]$ mplayer cachorros\ de\ juan\ villarreal\ -\ Amancio\ Garza.mp3

Running dmesg I can see some errors that are probably related:
