Download the latest Dante AVIO firmware with Dante Updater.

  • N/A (patch release)
  • ETS-6264: Audio drops in a Dante receiver when receiving from an AVIO in certain network configurations over time due to increase in latency. The increase in latency on the Dante receiver leads to dropped audio packets.
  • HD-1501: When the device is downgraded to the previous GA, it loses part of its persistence storage, including DDM credentials and DDM IP and port info. Workaround: Re-apply configuration settings that were lost after the downgrade.
  • CLOUD-1598: This is not a device side issue: This also applies if the device is manually enrolled in the DDM. After an upgrade, until the device is explicitly told about the DDM/Cloud FQDN the device will not be aware of it. Workaround: (1) Clear config and manually re-enroll; or (2) Unenroll, and use Dante Controller to manually enroll all devices.
  • HD-1502: This is not a device side issue: After upgrading from the previous GA (4.1.x), the local controller permissions are set to Prevent. The previous GA had incorrectly set the local controller permissions to NOACCESS. The new firmware sets the permissions to READWRITE. However, after the upgrade to the latest, the DDM is not automatically setting the local controller permissions to the correct setting. Workaround: (1) Change the local controller permissions in the UI to ‘Allow’; or (2) Unenroll and re-enroll and the DDM should set the local controller permissions back to ‘Allow’ in the UI.
  • TRID-581: No audio / interrupted audio from mobile device if the device is powered on from a cold start while the AVIO USB-C adapter is connected. Workaround: Disconnect the adapter from the mobile device, and reconnect it.

Audinate’s Support for Inclusive Language

To our customers: some of the terminology used in Dante products has been changed to align with modern usage. Specifically, areas related to Dante clocking now refer to “Primary Leader Clock”, “Leader Clocks” and “Follower Clocks” to describe the functions of each role more clearly.
