Tales of Symphonia music problem (sound OK)

[Pow3rus]

Hello! I play ToS with Dolphin 6325 and it works perfectly for video and sound (voice, battle...) but i can't activate the music because they are slow and with strange pitch.
Of course i can play like this but I want to know why the music is like that.

I have :
ASUS P5LD2-X/1333
Intel Pentium Dual CPU E2180 2.00Ghz
4Go DDR2 333.3Mhz
Radeon HD 4850

Please tell me if my problem come from hardware or if it's because Dolphin can emulate only SFX but not music.
