Many browsers have released an 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 Auto Play feature in your player to off, 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 turn the auto play off in your player.
Go to your stream or video and hit the Edit button, then click on the Design tab. If you scroll down, you'll see the toggle button for Auto Play. Click it to the off position, as seen below.
Hit Apply, and you're all set!
