I recently purchased a used VIZIO SV420M. Was extremely happy with the quality of the full 1080p HD picture. Was enjoying watching it when on it’s own the volume spiked to 100%. Pushing the volume button on the remote or on the side panel had no effect. The mute function would not work either. Thought for certain I was duped and had bought a lemon. Came to this site to hopefully find a solution to my problem. Went into the audio settings and turned off the True Sound feature, so far that seems to have done the trick. Thanks to all for this somewhat easy solution that I was not aware of. A very happy camper now!

Lots of good advice here. I had the fluctuating volume on my Vizio too, with the Vizio sound bar. I also have U-Verse, if you do too this might help as it solved my problem. I didn’t know this until I started poking around the U-verse settings, but there is an option to change audio settings in U-verse (Menu- Options- Audio Language Options- Digital Audio Output). When you get there the choices are Stereo or Surround Sound, select Surround Sound and save. When I did that the audio fading disappeared and the sound was MUCH better. I was able to leave Surround HD and TruVolume ON. Like I said I have the Vizio Sound Bar, whether this will work the same without it I don’t know but if you have U-verse this is worth a try.

Thanks for all the help! I’ve been having volume issues with this TV and it just gets so annoying to have to keep turning it up, and down, and up, and then down again. Usually when watching a DVD, when music comes in it’s SUPER LOUD and if someone is speaking over the music, you can barely hear them and it all blends together. But then when there is no music, the dialogue is super soft. I came here after trying to watch a movie (“Trust”) and the dialogue is all over the place. Aggravating!

I’ll try it with the TruVolume off–great and simple suggestion! I’ve spent so much time tweaking the levels in the equalizer but let’s hope this does the trick. Thanks again!

Glad i found this. I watch alot of sports, mainly auto racing and the volume gets crazy loud. You can barely hear the announcers over crowd and engine noise. I tried turning the TRUvolume off. We will see if it works.

I strongly suggest calling Costco Concierge service. They are very responsive and called Vizio while I was on the line and stayed on the line until I had completed my discussion. They are going to call me back in 2 weeks to make sure the update Vizio is sending in the mail fixes my problem (cutting out on audio while watching DVD’s).

Thanks for all the posts, I too have had the volume issue with my vizio but will try turning off the SRS. I love everything else about the tv but volume spiking is a big issue! Man up Vizio, you guys need to take care of this problem!

Glad I found this post. I purchased the XVT3D474SV (47″ 3-D) from Sam’s Club. Most everyone seems to be having the same problem with their set. Mine is doing the same thing with the volume fluctuations. I’ve tried turning off the SRS but hasn’t helped. The problem with the volume is very annoying and this unit will most likely be sent back. Looks like VIZIO would take the hint and fix this problem. Kinda sad having to take it back, I really liked the other qualities of the set.

I posted on the volume issue back in feb 09. long out of warranty now, but i liked all the rest of the tv’s features and performance enough to keep it. I still feel that vizio should have a fix for this problem though as the volume stabilization is why most of us bought these. DO YOU HEAR THIS VIZIO? Anyway, along with tuning off the SRS, changing the audio to “flat” in audio settings will help to make loud commercials less noticeable. To bad we have to keep tweeking these sets, i still might return it under the extended warranty.

I recently bought a 42 inch Vizio and had the same problem with the volume fluctuation. I followed the advice of others and turned off the trusound and that appears to have solved the problem! From what I gather, the trusound can work with some satellites, but does not work with the cable box. I went into the menu setting, selected audio, and turned off the trusound. Viola! I agree with others that Vizio either needs to eliminate this feature, or, at the very least, make it something that people have to turn on, not off, and then let them know up front in the operation manual. I was all set to take my tv back to the store and get a different one.

We bought a 55″ Vizio from Walmart and the sound is awful!! I have turned off the Truvolume as mentioned in previous posts. We will have to see how it works now.
