Modern web browsers have an auto-play policy to improve user experience and prevent media playback from starting without your consent. This policy affects how applications with alert mechanisms such as alarms or notifications can play sounds.
Due to browser policies, the alert sound won't play by default in browsers such as Safari, Chrome, Edge, and Firefox. However, the browser provides simple instructions for enabling the sound if users want to hear the alerts.
This policy means that the sound for the "A New Alarm Detected by System" alert in the Alarm Viewer page will not play by Default every time the Web Client Alarm Viewer page is loaded.
To enable sound for the "A New Alarm Detected by System" alert in Safari, Firefox, Chrome, and Edge, follow these steps:
In Safari
To always allow auto-play with audio:
Launch the Safari app on a Mac system.
Select Safari from the menu bar options.
Choose the Settings… option under the Safari menu.
Switch to the Websites tab within the popup window and choose Auto-Play in the sidebar.
Select the drop-down menu and your preferred choice. Selecting Allow All Auto-Play will allow auto-play with audio.
In Firefox
To always allow auto-play with audio in Firefox:
Click the menu button
and select Settings.
Select the Privacy & Security panel and go to the Permissions section (or enter Auto-play in the Find in Settings search box).
Click the Settings… button next to Auto-play.
Use the Default for all websites drop-down menu to select how you want Firefox to handle media Auto-play for all websites.
The default Block Audio setting will prevent Auto-play for all media with sound.
Click Save Changes after you have made your selection.
The setting you have selected will apply to all media for all websites except for specific Auto-play site settings.
In Edge Browsers
To Enable Edge to allow sound.
Open your Microsoft Edge browser's Settings and More menu by selecting the three dots at the top right.

In the left menu, choose Cookies and Site Permissions, then scroll down to the right and select Media autoplay.
On the right, a drop-down arrow gives you the options to Allow, Limit, or Block autoplay.
In Chrome Browsers
To Enable Chrome to allow sound.
Click View Site Information in the address bar of your Chrome browser.
Click Site Settings.
Under Sound, select Allow.
