Hi, the issue with 'earr*pe' is from the youtuber they often don't normalize volume and if they do they create ultra loud 'earr*pe' as a 'meme' especially people like pewdiepie they always did a really loud sound for comedic affect.
The only resolution to do that is normalize the volume on your site, as noise normalization requires such logic that it ties into your system drivers.
As for reddit it should be working if you granted the permissions as stated in the latest patch notes lmk.
