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 do not support multi-channel audio. If you use a 3rd party audio setup or a multi-channel audio configuration check to ensure that your sound is either stereo or mono. Surround sound and 3.1, 5.1, 7.1, etc. configurations will not work. If sound comes through when you plug in earbuds or headphones, this is often the issue.
