We have 33 Vizio TVs. We are using Plex to run the videos from the server but the issue is once the video begins we can’t control the volume. You have to exit almost all of the way out and change the volume and then go back into the program. THIS IS A PAIN!! Vizio said it was your issue. We just want to get the tvs working.
Please post this in the “Smart TVs (LG, 2016 Samsung, Sony, TiVo, Toshiba, VIZIO)” category and close this discussion. You will get better help there.
Sounds like commercial use, which may be a violation of terms and conditions of the Plex license.
This is not for commercial use. We are working with a client.
A client with 33 TVs in their house? Damn, I want clients like that ! 
Me too. A few coax/cat 6 installations for clients like that and I could have retired solvent and a much younger individual - with a boat.
