But this predicament forces me to have to use a 3rd party browser which stinks. I do sincerely prefer using Safari and staying within the Apple ecosystem when I can because of ease of use and simplicity. Even news sites (CNN Go, for example) has no issue. All of that taken together makes me think there is some DRM codec that just does not want to play nice with the new Safari at least not for me on my 4K iMac.Īgain, I'll mention that normal YouTube plays fine for me with no issues as do sites like Vimeo, etc. This is the same thing I experience on Netflix, HBO Max, Prime Video and Spectrum. Roughly 30 seconds into the presentation, the video portion went away and I could still hear audio.

In the ensuing time of waiting for something from Apple on my issue (going on 6 weeks) I noticed the other day in YouTube, whilst playing a movie ( YouTube Movies) the same phenomenon happened.

Also kill the coraudiod process in Activity Monitor. They've had me enable and re-enable the VP9 decoder in Safari (Develop Menu / Experimental Features). Last update was that my ticket was with a Senior Advisor at Apple. I had a ticket in with Apple Support and have not heard back from them in some time. Curiously, YouTube has no issues playing content. It's as though the stream is still going, just no longer playing video. When streaming content from Netflix, HBO Max or Amazon Prime the stream will start normally and after about 20-30 seconds the video goes 'black' but I still hear audio. Installed Big Sur in November and noticed an issue with Safari.
