NOTE
This issue is fixed in AVIO firmware v4.2.2.5 (released for Analog, USB, and USB-C) and firmware v4.2.3.5 (released for Bluetooth and AES3).
Please update your firmware using Dante Updater.
Affected products
There is an known issue affecting the following products and versions:
- Dante AVIO (all types, except for the install versions), firmware version 4.2.1.2
- UltimoX based devices, firmware version 4.2.8.2
Symptoms
After enrolling the device in Dante Director (or DDM, when enrolled directly from Dante Controller), it reverts to unmanaged mode after a reboot or power cycle.
This causes loss of audio, assuming the devices it is connected to remain enrolled.
Cause
- When an affected device is first enrolled after upgrading to the affected version, there is a bug related to the initialization of data storage.
- After a reboot, the device loses its server configuration, cannot contact the server (Dante Director or DDM) and reverts to unmanaged mode.
- Once the device is re-enrolled a second time, the data storage is properly initialized and the issue will not occur again.
Workaround
- Enroll the device in Dante Director (or DDM directly via Dante Controller, if this is the preferred method)
- Reboot or power cycle the device
- If the device unenrols and shows as unmanaged, enroll it again a second time
Validation
After completing the workaround, reboot or power cycle the device once more to ensure it stays enrolled.
Solution
Fixed in AVIO v4.2.2.5 (released for Analog, USB, and USB-C), AVIO v4.2.3.5 (released for Bluetooth and AES3), and UltimoX v4.2.9.10
