(GC) mario kart sound problems

[MaxBurnout1200]

on mario kart double dash the music will quit around lap two and stay off untill you restart dolphin. It just quits on all modes: single player cup, timetrial and even 2 player.

I have used diferent plugins and sound configuration but always have the same problem

Is this not fixable or can it be fixed

Also when the music is on its fairly low compared to the actual gamecube, I mean the ratio of music to sound effects
