a sound problem

[猫行天下]

Hi,everyone,

I'm not sure why this happens, but the problem is when I'm in the 
GUI(Gnome),the sound works pretty good. And if I play a music and change to the 
console, while Login into the system,the sound is also works good. But when  I 
first changed into the console and Login  before there is any music 
playing(after boot), I can't sound it.

How can I deal with this problem? Thanks for any thoughts on this.
