[SierraKen]

Thanks Steve. I changed the lines you talked about. I still don't know hardly anything about this, but if there is anything else I should change, please tell me. You also might want to update the Wiki page where I found this example code at, which is here: https://qb64phoenix.com/qb64wiki/index.php/MEMSOUND

Here is the update:
