Many browsers have released a new update that automatically mutes all audio in their browser when using autoplay. Unfortunately we cannot change this, it is simply a feature in their browser.
In order to work around it, we recommend setting the player to Autostart = No, and force your viewers to actually hit the play button. This will allow the video to play with audio.
Here's the step by step on how to set your player to Autostart = No.
Go to your stream or video and hit the Options button, then Edit. Go to the section that has the player, and you can set the Autostart option to No.
Hit save, and you're all set!
