Starfox 64 ntsc sound glitches

i'm having trouble with the game Starfox.
i experiencing scratchy background noises and distorted explosion sound effects on the level "Fortuna , former defense post".
My dump is ntsc, id: [A7D015F8-2289AA43-C:45], Goodn64 and the pj64 rom database says it's correct.This audio issue occures both with jabo's and Azimer's audio plugin.

Any suggestions?

Here is a sample of the audio issue:

thanks for the idea, no success.I think this problem is more serious.One can often hear unwanted noise when running a game with more than 60 vl/s but these noises are extremly bothering.
