Thanks. Yes I have I tried most if not all of the settings in different states. i,e on/off . Restarting the browser each time and it made no difference. Also it is not just videos from YouTube. For example there are videos from users on Twitter where some work and some do not.
I do get that same message you get when I visit the link you posted.
I wonder if it has something to do with CODECS???
This topic has been discussed here before and has never reached a resolution. My take is that this occurred when I upgraded to the current version. Video sound always worked before that in the older version.
I really believe there is something in the code that is causing this to happen.
For one video to work from the same site and same user (as in the examples I posted) and the fact that I have sound on system files on the PC to me indicates it’s on the Brave end.
