Troubleshooting Common Issues
Audio Issues

If you can see the video but can’t hear any sound, it could be a problem with your speakers or your volume controls.


OTN is not responsible for link or connectivity issues when the client site has used all available bandwidth locally. It is advised that you contact your OTN Account Manager if you suspect that your media streaming event will saturate your internet link prior. OTN webcast event administrators will tune your event to suit the audience volume with advanced notice within the capabilities of your available bandwidth. Please be advised that the default configuration of each event is set to 720Kbps. If you do not know what the impact of a media streaming event is on your internet connection, please consult with your local IT department and your OTN Account Manager.
