Check the settings in the AES67 Transmitter block and note the multicast address. For example:
When you add an AES67 Transmitter to a design, the Multicast Address defaults to 239.69.xxx.xxx. When you reboot the Core or push a design, the Core creates random numbers for the xxx.xxx values. Since a device receiving AES67 audio is listening on a given IP, if the Core changes the transmitting IP, the receiving device no longer receives any audio.
There are two ways to prevent a Core from changing the stream address:
- Replace the "xxx" with values to create an IP address. These values must create a unique multicast IP address that is not used by any other stream in the system.
Look at a device that was receiving this stream to see if the stream's IP address is indicated. If so, use it for the Multicast Address.
- Change the Connection Mode property of the AES67 Transmitter to "Manual" mode. Then, save and run the design to the Core again.
After you make one of these changes, re-assign the stream to all receiving devices to ensure they are using the correct stream IP.
