Not sound

The idea for this plugin is great because it is a part that is very missing in WooCommerce.
When I receive an order, a pop-up appears and that’s great. However, there is no sound.
I have reviewed all the topics and seen that several users have the same problem.
That is a very small percentage (out of 2000 users), but this is the problem that the largest number of users have, it would be good to find the cause because this plugin without sound is unusable.
It is clear that the Admin cannot look at the screen every minute to see if there is a new order.
