pitch changing? (macromedia flash 8)

[P3drob]

so I know that there are people who actually managed to solve the error but for some reason a little while ago the sounds that I put in the animations didn't even make the sounds with the lowest pitch, and I already tried to use the tips that people gave to others but it didn't help much, I tried in Adobe CS6 but it had the exact same error, help me please I've been trying to find the solution for more than 2 days
