I'm stumped here, but I've also never really done add-ins before. I've got a custom set of forms that use barcode input I'm working on. The plan is for the users to be working with Zebra TC56 barcode scanners running the NAV Android app. I've got things working except for a request for audio feedback. If there's an issue with the scan they'd like the device to make a sound to alert them. Any pointers on how to make this work? Currently on NAV2016 CU15.1.
