1. Check Your Camera’s Audio Codec
Note: This section provides general guidance only. For detailed, step-by-step instructions, Coram recommends that you consult the manufacturer documentation provided with your camera.
Access the camera’s web interface, and log in using admin credentials.
Navigate to the Audio or Sound configuration section and identify the current audio codec settings. For example, G.711A or AAC.
If required, change the setting to a codec that works with Coram. Use the table below to check compatibility.
Save your changes and reboot the camera if prompted.

AAC | - Rich, natural sound | - Supported by many newer IP cameras |
Note: Audio compatibility also depends on the camera you are using. For more information, refer to the documentation provided by the camera manufacturer.
2. Verify that Audio is Being Recorded
Access the Coram web app and sign in to your account.
Access the Timeline view for the camera. To learn more, refer to Introduction to Timeline View.
Confirm that audio is enabled for the camera, that the video player is unmuted, and that the device you are using to access the video is configured for audio playback.
If no audio is present, test this process with different codec settings.
3. Update Camera Firmware
Outdated firmware can cause compatibility issues. Visit the camera manufacturer’s website to download and install the latest firmware.
4. Contact Coram Support
If the issue persists, gather details about your camera, such as the model, firmware version, and current settings, and contact Coram support for assistance.
