I kind of figured I wouldn't get a response here to this, so I'll pass on to people some info. I DL'd the bin file and put it on a clean new sandisk usb stick. Nothing on it except for the bin file. The bar would not even try to take the update, so I called support. The end result is they are sending me the update on a usb stick. Two things I've learned from them- buy a stick no bigger than 2gigs and don't sweat fat32, as most sticks come formatted. Maybe it's picky about the stick too, who knows. They're sending me one with the bin file, so we'll see.
I did everything correctly, except the post update diagnostic check to see if firmware took, with the specific sequence of lights lit,
revealed only a few lights lit - defiantly not the sequence the tutorial guide shows...
I wonder if your soundbar, like mine - the S4251w-B4 - IS the factory updated version (if the are two versions, one pre-fix and one post-fix?)
and that's why the update is not working because it already has the correct firmware?
--> Did you specify to vizio tech that you had the B4 version? And they still, apparently, are assisting you to update the firmware, huh? So maybe there is only 1 single hardware version and they all have the flaw that the firmware update is aiming to fix...
Good Luck - I may call them as well. I used an 8GB USB 2.0 thumb drive, btw.
It might very well be that I have the most current update too. I suspect I do actually, because I don't have the earlier problems where sound went out switching inputs. But I do have intermittent audio dips and tv channels have lost audio on occasion. I channel up or down and it comes back. I'm never forced to restart the sound bar. No harm in trying to update even if the firmware is the same. All I know is their stick with it should work. Give them a call. And yes, I did go through with them my exact model. They even walked me through a couple tries. Did you get 6 lights and then 12 lights at least, which suggests that the firmware was loading? Anyway, we'll see. I also grabbed a new and better optical cable. Could be that too. LOVE this system though. Watched Avengers today on netflix...man that sounded awesome.
I thought the same thing about FAT vs. FAT32. I've formatted 4 USB sticks with a wide array of sizes (ranging from 64 MB upwards to 16 GB) and with a varying combination of FAT and FAT32. As you probably noticed, the instructions for installing the firmware update are not rocket science.
None of the drives with the firmware loaded have been successful at installing. You simply plug the unit in (with the USB stick connected), it blinks momentarily (as if to say, "hey - I'm reading the USB stick hang on"), and then does nothing. Goes into sleep mode. It does not light up all 12 LED's as specified. Pressing the two buttons on the side of the unit to have it display the firmware version does not produce the expected result . . . I think only 3 LED's were illuminated.
Vizio cannot tell me if the new units are being shipped with the correct firmware or not . . .
The reason I tried installing the firmware is because I, too, experienced momentary dropouts in sound. Annoying. I can't say that they were often, but they're a pain.
Do you recommend upgrading to an optical cable to something other than the stock one they included in the packaging? I cannot discern whether the one with the unit is of good quality or not.
If anyone has any updates regarding this issue, I'd appreciate a reply.

What I have found is that the momentary audio dips only happen with the cable box when watching cable tv, movie channels, and on demand. In short, anything cable is broadcasting. Nextflix and hbo-go via chrome cast never ever has this happen. Only cable, which tells me that it isn't the sound bar or tv- another reason I haven't tried the firmware update again. If the sound bar or tv was causing it, I would think it would do it all the time no matter what is being broadcast. I have also found that it can happen more frequently after the tv has been on all day and night. If I want to get into movie watching at night on premium cable channels, I turn the tv off and back on- a reboot. That seems to clear the problem for the rest of the night. It could have something to do with digital errors maybe. I have a new hdmi cable that I haven't tried yet, nor have I tried switching hdmi inputs on my tv, and I've been using a new optical cable of better quality. I mostly gave up because it's that pesky 'intermittent' problem that can be futile to track down. I have also tried optical straight from my cable box and have the same issue with momentary audio dips. It's infrequent. And rebooting the tv does seem to clear it if you've had the tv on hours and hours and it acts up. But it really is infrequent and not enough to get blown out about, but just enough to make you want to try and solve it regardless.

I was reading the comcast forums and audio drop outs happen to be a known issue of their X1 boxes made by Pace. Allegedly, the Newer X1 boxes mfr'd by Motorola/Aris DO NOT have the Audio Drop Out Glitch...
So you MAY be onto something thinking that the audio dropout may be related to your Cable box - I suppose possible even if a different provider than Comcast and Very Likely if you too happen to have a box mfr'd by Pace (do not know if Pace is a Comcast exclusive hardware mfr or more likely, make cable boxes for most/all major Cable TV Providers....
Just thought I'd bring that up is all, when I read your eluding to the possibility of it being Cable Box/Provider, ect vs our Vizio Soundbar
---> Because the drop outs do seem to be exclusive to Cable TV source, not occurring with my xbox 360 or my Panasonic Viera (streaming local videos) ...
One thing is for sure, in the four months the system has been in line, I've gotten VERY spoiled. Going back to the tv speakers is like listening to tv through a transistor radio. Horrid. So for the investment, this has to be made right. But in large part, because of the awesome sound that it does deliver too.

All in all, vizio delivered a new system to my door with mostly a minimum of hassle. I score them a B at this point for that. Of course their first bar that failed I score an F, so the grades aren't spectacular thus far. But I have a working system again. We'll see how this one does. I'll take a few days to make sure it's not screwed up in any big way and then send the busted one back, least I get charged for that! The S4251w-B4 has a couple quirks, no doubt. But it does have really good audio and the surround with the rear speakers is truly a delight. I couldn't, wouldn't watch a movie until the new bar showed up. It was missed that much.
Also my rear speakers (the ones which connected to the sub) have a lot of noise in them, even if something is playing you can hear the noise.. It can't be normal can it?
Plus sometimes trough (HDMI then Optical) I can't get the surround to work, it only plays front (surround is on). Say I'm playing a YouTube video with possibly mono out, it comes only on front bar.
I bought mine in Dell
Been having the exact same problem since day one. It's almost like the subwoofer sort of 'creeps' up on its on... but like you said, just moving the subwoofer level down one notch returns it all back to normal.
Been looking for a fix for this for almost two years. It's pretty frustrating to have to keep the Vizio remote within reach at all times, just to fix this regularly. :-/
