Disable Tab Audio Auto Muting

[Admini]

I really apologize for taking up your time. for some reason i thought it was the auto mute feature in chrome, which there have been publications about.
Indeed, it was the extension and its setting that did it, which i would not have even thought could be the cause.
Thanks so much for your reply and forgive my stupidity
You are a very responsive developer, thank you for your amazing work.

By the way, the extension that was causing the problem is called: YouTube Mouse Controls Settings.
Very handy extension, for fast-forwarding and fast-backwarding videos using the mouse wheel.

To fix the problem, you need to disable it in the settings:
"Attempt to fix the lag between the player volume and this script"

Glad to know it was solved.
And thanks for the hint.
