Source for Vizio soundbar schematics

[Dr.HowardFine]

I recently purchased a Visio S3821w-CO soundbar with a wireless subwoofer second hand.

However, I just discovered the subwoofer is a model S3851w-D4. (ie : NOT S3821)

As a result, I've been unable to pair them together, even though I've downloaded the manuals for BOTH models, and tried the (very similar) methods described in both.

I'd like to try to get these to pair, but they appear to be incompatible, in spite of being in the same product FAMILY and vintage.

I contacted Vizio support, but they were not very helpful - only being able to read the same user manual that I already did.
I asked if they could send me schematics, but said they are not available to the general public.
Being an EE in the audio industry, I thought I might find a way to MacGyver either the soundbar or subwoofer to let them pair.

I'm hoping someone here can direct me to someone/someplace where I might get hold of the schematics for these.

Anyone ???

I bought the vizio one about a month ago and have really loved it, lots of inputs, bluetooth streaming, and also I really loved the wireless subwoofer path more than a wired one. I'm sure the sound quality won't differ much between the two as all soundbars in this range tend to be pretty similar, but have to just decide based on the features.

Nice thing about a wired sub is that if you want to upgrade it you can, although most of the time if you're looking to upgrade a sub you're looking to upgrade your whole system from a soundbar. For me the convenience of wireless is nice because I move my soundbar from room to room when we have people over so this is very easy to do and aesthetically pleasing. Another thing on the vizio i can vouch for is the DTS Truvolume and the DTS Trusurround which I think gives it an edge sound quality wise over others. Overall they're both quality brands but the strong rep Vizio has with soundbars and simplicity of it all sold me
