问题
I'm building a kiosk media which runs on Chrome that plays video with audio. I know that chrome by default only allows autoplay for videos with muted props.
And i know that i WAS able to override this by enabling a flag in chrome via chrome://flags/#autoplay-policy
I have just updated to Chrome 76 and this flag seems to be gone and the autoplaying of video doesn't seem to work anymore!
Any idea how do i overcome this?

I just spoke to some developers from Google about this issue recently. I submitted a bug. They have been very helpful.
Even though autoplay policy chrome flag was removed in https://chromium-review.googlesource.com/c/chromium/src/+/1593800, you can still run Chrome with a specific autoplay policy from the command line.
Autoplay policy that does not require any user gesture.
/Applications/Google\ Chrome.app/Contents/MacOS/Google\ Chrome --autoplay-policy=no-user-gesture-required
They say this command will stay, so that's good but even better Chrome allows you to always enable autoplay by explicitly allowing a website to make sound "Site Settings > Sound"
Good luck.

You can use command line code to execute chrome in kiosk mode with no-user-gesture-required:
google-chrome-stable --kiosk http://google.com/ --new-window --start-maximized --incognito --autoplay-policy=no-user-gesture-required --disable-features=PreloadMediaEngagementData,AutoplayIgnoreWebAudio,MediaEngagementBypassAutoplayPolicies &
