(In reply to Jani Uusitalo from comment #6)
> ### Steps to reproduce
> 
> 1. Open about:config
> 2. Search for autoplay in the settings
> 3. Set `media.autoplay.default` to `1` ("Block Audio", which is the default)
> 4. Set `media.autoplay.blocking_policy` to `2`
> 5. Open a Twitch VOD, for instance https://www.twitch.tv/videos/280106033
> 6. Try to unmute the video (either by clicking Twitch player's speaker control button, or by dragging the accompanying volume slider)
> 
> ### What I expect to happen
> For the audio to be unmuted.
> 
> ### What happens instead
> The audio remains muted, and the volume control/indicator remains in the muted position.
> 
> ---

> I'm unmotivated to report this to Twitch, as I'm unsure about the precise meaning of `media.autoplay.blocking_policy`, and I currently don't use the non-working value for it myself. Feel free to downprioritize this as you see fit, unless the original reporter is still affected. Here's [my downstream report over at Launchpad](https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/1874808) though, just for reference. (I'll update it too.)

Still suffering from this issue 4+ years later.
