Edit.

maybe you have only
==========================================================================
Opening audio decoder: [mpg123] MPEG 1.0/2.0/2.5 layers I, II, III
AUDIO: 44100 Hz, 2 ch, s16le, 320.0 kbit/22.68% (ratio: 40000->176400)
Selected audio codec: [mpg123] afm: mpg123 (MPEG 1.0/2.0/2.5 layers I, II,  
III)
==========================================================================
AO: [alsa] 44100Hz 2ch s16le (2 bytes per sample)
Video: no video
Starting playback...
A:   3.0 (03.0) of 231.0 (03:51.0)  0.3%

and still no sound

Then (you can use an other terminal)
$ alsamixer
Use [F6] to select the right soundcard and make sure the volume levels are  
set to 100
