Problem: new voice entry crash

I added a new system, and spliced a voice entry for specific voiced that will be refering to this system.

I added the new .wav file into the voice's .utf archive, under the hash of it's "msg_id_prefix" (gcs_refer_system_EW07; 0x83982148 ) and set a patrol to this jump hole.

Now, whenever I enter the system in which the jump hole is located, the game crashes. FLSpit says nothing about this hash.

Any help please?
Thanks.

3D sound is on, but if it only works when it's off then it's no use.
Point is, I replaced sound entries in the past and it worked with 3D sound. But when I added a new one, it crashes. maybe it's about the quality?

I triple-checked it, looks fine in all means of code.
You can check it if you want:

Other patrols and zone populations work perfectly.

I'll try to add adoxa's mp3 codec fix, maybe it'll work.
EDIT: It didn't. I'll try to re-export the file from the editor.
EDIT: That didn't work either. I have no idea what's wrong.

I mabaged to get it to work after adding the value to voices_space_male under "msg = gcs_refer_system_EW07-", changing the hash id also with the minus in the end. apparently the minus is important...
Sorry for wasting your time, and thanks for trying to help
