Troubleshoot issues with embedded audio via AJA video I/O devices

If you encounter problems capturing embedded SDI sound and/or outputting sound to an SDI monitoring device via the driver of your AJA Io 4K Plus or AJA Io X3, try the following steps to troubleshoot the issue:

  • Set the AJA audio device as audio output device in Livegrade’s audio settings
  • Open the AJA Control Panel and go to “Audio Mixer”
  • Ensure to set
    • “Capture Monitor” > “Host Audio (OSX Core Audio)” > “On”
    • “Playback Monitor” > “Host Audio (OSX Core Audio)” > “On”

Audio mixer settings in AJA Control Panel

  • Restart Livegrade, so that the new audio configuration takes effect
Note: You must also ensure that the audio of your playback or live monitoring signal is not muted. For example, the audio meters in the toolbar should be colored during playback or live monitoring.
