Probably I compiled the file with stereo output and not mono since usually the default option is stereo.
EDIT: Lol now don't laugh at me but I found the error... In the sound path I put
sound[] = {"Sound\GeigerCounter.ogg", +10db, 1.0};
instead of
sound[] = {"\Sound\GeigerCounter.ogg", +10db, 1.0};
and the game couldn't read the path correctly
