Also, just in case there's still doubters, in addition to
electrically dissecting the TRN 8-core cable in
post #1626, I also
physically dissected the same cable to be
doubly sure.
The physical dissection will add a
2nd layer of proof, and I hope it will rule out factors such as me having a defective multimeter, not knowing how to tin wires, not knowing how to check continuity with a multimeter, being an incompetent idiot, etc.
So here we go.
First off, here's proof I tinned the wires when I did my original continuity testing with the multimeter. Sorry, the focus on my macro lens has a very narrow DoF, so I could only focus on 1 wire at a time. But as you can see, I know how to properly remove wire enamel and tin each wire:
Next here's the plug before I started the physical dissection, just to prove it's a genuine TRN plug (note the logo):
I used a Dremel cutoff disc and carefully cut the metal shell (being careful to ONLY cut the metal shell and NOT to cut into the wires whatsoever):
Next I carefully nibbled away at the plastic (or hot glue) or whatever it is that encases the wires, millimeter by millimeter, using high-powered jeweler's optivisors to carefully watch my work under 10x magnification. Again, being ultra careful NOT to cut into the wires whatsoever. Once I removed the majority of material, the wires were bundled together with a piece of masking tape (a normal method to help make cable assembly/soldering easier).
When I peeled away the masking tape, I discovered the 1st of the 3 'not connected' wires. The other 2 were a little lower down in the wire bundle, where the remainder of plastic (or hot glue or whatever) is still left. I'll remove the remainder of that material in the next step.
Once I had removed the very last little bit of plastic (or hot glue or whatever) was left, the last 2 of the 3 'not connected' wires fell away. I also exposed the actual solder terminals, as shown.
And just as my
electrical dissection determined that there was (3) yellow ground wires, 1 silver L+, and 1 silver R+, my
physical dissection backed it up with more proof. Here is a closeup of the 3.5mm plug terminals, so you can see which wire is soldered to what TRS jack terminal. The modders and cable builders amongst us will recognize that everything is there, properly soldered to the terminals, not tampered with in any way by me, and that my electrical analysis from post #1626 was accurate:
So, I hope I showed that my evaluation of the situation was done in a professional, non-biased, and factual manner. If you notice something I missed in my physical dissection, please let me know.
