I'm hoping to create an audio alert / notification that plays when a new customer is created. 

Our Odoo instance interfaces with a custom front-end customer mobile application. Each time a new customer places an order, then the Sale Order is created using the customer information and order details captured from the front end, via an integration.

We like to give new customers a welcome treat with their order, but we keep missing new customers because we don't have an active alert to notify the warehouse team that this is a new customer.

Any help on how to do this would be much appreciated!
