Parasite eve 2 problem sound PC

hello everyone I create this subject because I have not seen another that dealt with this problem.

I’m sorry for the quality of English, I speak French so I translate with google

Here is my problem I made a video so that you can hear the sound bug that I have at the beginning of the game load my save and then further by fighting N ° 9 the sound crackles loudly

I shared my parameters in the video but here they are again

I play with the core playstation Beetle PSX HW

of course I tried a lot of different parameters but never solved

Does anyone have a solution to my sound problem? thank you in advance

this is my first subject so please be indulgent with me
