Tech Notes

FAQs

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.

Upgrading Firmware via SD Card

To download the latest codec firmware visit www.tieline.com. Copy the firmware file onto a FAT32 formatted SD card and then use the following procedure to perform a firmware upgrade. Note: A single partition FAT32 formatted SD card must be used.

  1. Disconnect all connections before attempting the firmware upgrade.
  2. Insert the SD card into the SD CARD SLOT on the front panel of the codec.
  3. Press the SETTINGS button.
  4. Navigate to System and press the OK button.
  5. Navigate down to Firmware and press the button.
  6. Navigate to the firmware file and press the OK button to commence the upgrade.
  7. Update progress is displayed and when complete the codec will automatically reboot.

Upgrading Firmware via the Toolbox Web-GUI

To download the latest codec firmware visit www.tieline.com and save it to your PC.

  1. Disconnect all connections before attempting the firmware upgrade.
  2. Open the Toolbox HTML5 Web-GUI and click Settings in the Menu Bar, then click Firmware to display the Firmware panel.
  3. Click Browse firmware to search for the latest firmware and download it to your computer. Note: the Download firmware and Let codec download then install firmware links are only visible if firmware more recent than the currently installed version is available.
  4. Once the firmware has been saved locally, click Update from a selected file in the Firmware panel.
  5. Select the .bin file you are using to perform the upgrade and click Open to start the upgrade. IMPORTANT: The codec will reboot automatically after the firmware upgrade. DO NOT remove power or reboot the codec before the update has completed and the codec has rebooted itself.

Important Note: We recommend clearing your browser cache after the upgrade is complete when using the HTML5 Toolbox web-browser GUI to control codec functions. The short cuts for this are:

  • Google Chrome: shift+Ctrl+delete
  • Mozilla Firefox: Ctrl+shift+delete
