This section explains the steps you need to follow to enable the start-up tone in Chrome OS, with pictures of the screen to help.
1. Click on the Time widget in the bottom right corner to open the System menu. Click on the Settings button.
2. Click on the Menu button in the Settings window and select Accessibility. If you can’t see this option, click Advanced to reveal more menu items.
3. Click Manage accessibility settings.
4. Scroll down to the Audio section and click on the toggle switch for Play sound on startup to turn it on.
Note: If this does not work it could be because your computer settings are managed by someone else (an IT department or administrator for example). If this is the case, you will need to contact them to access these settings or for further help.
