Multi-Channel Audio Boost is not Changeable...

I had alot of Low Sound issues, and after a bunch of Research I found that setting " Multi-Channel Audio Boost " to Large mostly resolved that issue. However Sometime in the recent history the issue returned. So i went back to check the setting again and it’s now set to None, and I cannot Change it.

Any thoughts?

Never Mind, It turned out to be an issue with the Browser. Still troubleshooting it, but it’s not a PLEX issue.
