Some things to check if AES67 streaming is not working include:

  1. Check the PTP clock synchronization in the Tieline codec and the device to which it is streaming and confirm they are locked and synchronized. This is verified in the AES67 Synchronization panel in the Tieline codec’s HTML5 Toolbox web-GUI.

Destination Stream Troubleshooting (Device to Tieline)

  1. Ensure the global digital input setting is configured for AoIP and not AES3 via the Audio Options panel > Digital Input Type [Audio Over IP (AES67)]. To configure this via the codec front panel press the SETTINGS > Audio Options > Input Type > AoIP.
  2. If audio is still not being received from another device double-check that the input itself is configured for digital audio and not analog (only for inputs 1-8) in the Inputs panel. This can also be checked via SETTINGS > Audio Inputs [Select input] > Type > Digital.
  3. Confirm all settings match the device streaming audio to the Tieline codec. E.g. Audio Sampling Rate, Audio Sampling Depth, Packet Time, Number of Channels streamed.
  4. Confirm the stream Status is Running.

Important Note: PPMs on the AoIP Destinations panel are inactive if the Digital Input Type is not set to AES67 and the corresponding input Type is not set as Digital.

Source Stream Troubleshooting (Tieline to Device)

  1. Ensure audio is metering on the outputs streaming to the other device. Note: When streaming in AES67 mode, the Matrix Editor hard coded output channel assignments depend on the stream configuration mode. See Configuring AES67 Sources and Destinations for more details.
  2. Confirm all settings match the device to which audio is being streamed by the Tieline codec. E.g. Audio Sampling Rate, Audio Sampling Depth, Packet Time, Number of Channels streamed.
  3. Confirm the stream Status is Running.
