Tonight I get no sound :(
I went through similar problems with an M507-G1, basically the 50” model of your 65” TV. They updated the firmware so that really basic things that ought to work all the time, like sound, would just… not work sometimes. And I didn’t sit down to play a game of “can I make the TV work tonight?”, I sat down to watch some specific program. I ended up getting rid of my two year old Vizio (had kept previous TVs for 10+ years) and bought an LG C1, which Just Works all the time (you know, like you’d expect any TV to do) and it’s great, but I hadn’t expected to spent money on a new TV for at least another five years. Vizio cost me money and aggravation, and I’m never buying anything from them ever again. More on reddit.com

r/VIZIO_Official on Reddit: Tonight I get no sound :(
January 19, 2022 -
Get home after and evening out and put on the Vizio TV and no sound. I press the Volume Up/Down and see the Vizio Soundbar recognizes the buttons as the lights go up and down. But no sound.
I switch the Inputs to a different HDMI. No sound. I try various inputs. No sound. I restart the Vizio TV. No Sound. I power off and on the Vizio Soundbar. No sound. I try the Inputs in the sound bar from HDMI -1 to HDMI Arc. No sound.
I have my son unplug and replug the power to the Vizio Soundbar as this is generally the last resort that kicks things in gear. No sound. All the whole I can turn the sound up and down and see the lights show a response but…No Sound.
I finally have the Vizio Soundbar recognize the Apple TV has been on the whole time I have tried HDMI-1 and instead the Vizio TV thinks I’d prefer SmartCast or FreeTv (or something that sound stupid). This time it recognizes the Apple TV and I see that screen so I think great when I switch back to Cable I will have sound. I saw the Vizio Soundbar blink when it realized the Apple TV was there, surely it will understand when I switch HDMIs and I will have sound with Cable. No sound. I switch back to the Apple TV. No sound.
This has gone on about 20-25 minutes. Less than 2 years old the Vizio TV and Vizio Soundbar and neither one works 25-50% of the time. This is a giant waste. Tonight I have Silence.
This TV and Soundbar should be great Vizio is a name I know not some knock off store generic brand. I spent a decent amount of money on this and I get nothing. No sound. Sometimes No Picture. Sometimes it all works and then just cuts out randomly and restarts. Occasionally it all works nicely. I wish the Features of the Vizio TV and Soundbar would have said you’re giving us money to not have a working products — Enjoy No Sound.
Vizio M658-G1 4K HDR Dolby Vision TV
Vizio SB36512-F6 Soundbar with Dolby
the above products are fully updated (which seems to be how the products slowly perform the jobs they should)
I’ve reached out to Vizio support (during the height of the Pandemic I was given zero support and told to check online). But now I am told “yeah this doesn’t sound good it may not work…do you have an extended warranty? Otherwise we can’t help you.” It seems so odd to think less than 2 years is all they think their products are good for. Why does the consumer need to buy extended warranties just so the garbage we buy will work as it should in a timeframe one would expect.
Tonight: No Sound. Silence. Maybe this is the sound of silence.

Do you get sound through the TV (disconnect the sound bar)? My M658-G1 is still running strong, but I haven't run updates in at least 18 months (I've disconnected it from the internet as I don't use it for streaming and I saw people having issues getting service during the pandemic).
