Audio Card Firmware Update

The latest generation of BTIR2 features an AES67 daughter board that fully supports AES67, ensuring compatibility with Dante™. Additionally, these devices have mDNS discovery enabled, allowing them to be detected in the Dante Controller, similar to a Dante product.

However, starting with Dante Controller V12, a pop-up message may appear indicating that unlicensed Dante™ products are being used. To address this, the new firmware will disable Dante™ discovery, and all R2 units will be recognized as AES67 devices.
