Hi @Gary Bouchard ,
Could you please test other media apps for the mute option? The mute option works well on my end.
If the mute option does not show up in other apps as well, I suggest you try repairing Microsoft Edge at Control Panel --> Programs --> Programs and Features --> Right click Microsoft Edge --> Change.
If repair won't fix this problem, I suggest you send feedback (Alt+Shift+I in Microsoft Edge) to the Dev Team to report this problem. Thanks for your understanding.
