Comment 24 for bug 125739

For we it worked installing the following packets:

mpg321
ubuntu-restricted-extras
libasounds2-plugins
esound
mpg123-alsa
mpg123-esd

After a nautilus restart the problem disappeared.
I didn't install Pulseaudio, I installed it in an other system and it messed up audio in applications such as xmms and skype.
I agree with jean Azzopardi that esaound is the key to fix this issue.
