If you are not hearing sound in TestOut's videos, please try the following ideas:
- Please ensure that the browser tab is not muted and that webpages are permitted to make sounds.
- Right click on your volume icon in the system tray and open the volume mixer. Ensure that nothing is muted there.
- Ensure your speakers are turned up and turned on.
- TestOut's videos only support single channel audio. If you use a 3rd party audio setup or a multi-channel audio configuration check to ensure that you are set to use audio on only a single channel. If sound comes through when you plug in earbuds or headphones, this is often the issue.
Chat in or call us for additional support, if needed, at 1-800-877-4889. We are open between 6:00am and 6:00pm Mountain time, Monday - Friday.
