What is the default behavior for a unicast audio subscription in Dante?

The default behavior for a unicast audio subscription in Dante is that it is the expected and standard operation for Dante-enabled devices. In Dante networks, devices can subscribe to audio streams using unicast communication, which is a point-to-point transmission method where audio is sent directly from one device to another.

This functionality is built into the architecture of Dante, which is designed to facilitate seamless audio routing with minimal configuration required from the user. As such, when devices are connected to the network and are recognized as Dante devices, they will automatically be capable of handling unicast audio subscriptions without the need for extensive setup or manual intervention.

The other options presented do not accurately reflect the default capabilities of Dante devices. While some Dante devices may have specific features or limitations, the ability to utilize unicast audio subscriptions is a core function shared across the majority of devices in the Dante ecosystem. Therefore, anyone familiar with Dante technology should find that unicast audio subscription is inherently supported as part of the system's default operations.
