Pb with Minecraft music

[light62]

Hi everyone, 

 

So I have a problem, in the sound options, my my music and sound level are setup at 80%, but i just have the sound when I hit a mod or break a block. I don't have any music when i play. 

Have you a solution ?? 

 

P.S: I used a Sphax texture pack?
