Some things to check if AES67 streaming is not working include:
- 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)
- 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.
- 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.
- 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.
- 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)
- 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.
- 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.
- Confirm the stream Status is Running.
Please see the following pinouts for RJ-45 adapters that can be used with the codec. Please note the codec does not use +/-15V on pins 7 and 8. Image courtesy of AngryAudio and StudioHub.
MPX connections are sessionless so do not use a session port. However, monitoring connections associated with these connections that connect over regular IP stream connections require use of a session port. The default ports are as follows:
UDP audio port 8854 is the default for MPX Stream 1 connections (Raw uncompressed and MicroMPX).
UDP audio port 8874 is the default for MPX Stream 2 connections (Raw uncompressed and MicroMPX).
TCP port 9002 is the default session port for Monitor Stream 1 and Monitor Stream 2 connections. Ports 9010 and 9030 are the default audio ports.
