Setting this to a partial release status as the majority of ads on web and TV apps should now have normalized sound. We are still continuing the work on this and will update the status again when it is fully complete!

Twitch, please address this. I watch streams at work. When I suddenly get ads, which are dramatically louder than the stream content, I am driven to (a) mute the ads or (b) stop watching completely. Also, you're required to normalize ad volume by law: https://www.fcc.gov/media/policy/loud-commercials
