0's and 1's will always be there. Now since HDMI doesnt use a "secured" connector I can see a loss of info under vibration. But as with all digital its either there or its not. There is no form of grey goo in the middle.
I thought we explained all of this. But here is a quick summary again.
The 1s and 0s are recoverd correctly as you state. No one is debating that one way or the other.
Sometime later, for audio, those samples need to become analog signals. The DAC needs three things to do that:
1. The sampe value. This is 100% there per above.
2. A reference voltage. This voltage is divided by the value told to output (more or less). This is an analog value. If this value is wrong, your output is wrong. If the value gets modulated (modifed) by something, then your output gets distorted.
3. A master clock. This tells the DAC when to output the samples. This clock must have accuracy down to trillionth of a second (based on math) for the last bit of a 16-bit value to be accurate.
High-speed activity on power supply lines and RF leakage/cross-talk cause #2 or #3 to ever so slightly change. When they do, you no longer have the same output. The characteristics of the cable (and noise induced on it) impacts the circuits at both end and that impact in return can modulate #2 or #3.
I hope everyone is in sync with above. I post papers outlining them.
What the disagreement is whether that impact is of any audible significance. The effect though on #2 and #3 can be measured and shown with instruments.
Net, net, we have an analog process when it comes to timing and clock for audio. The system is not all digital. It never has been despite misconceptions to the contrary.
Taking that info and passing over a $3.50 monoprice cable, vs a $800 snake oil brand, you aren't gonna see a difference, there is no interference... its either gonna show up, or its not.
I buy monoprice cables also. So that is neither here nor there. And for video, there is no issue because the final output is more or less digital (a pixel). So nothing "shows" up anywhere if you change HDMI cables.
Take what ya read about the intergrity of digital, especially when it comes to outside interference, with a grain of salt...
BTW I have years of experience in the IT field working with DSL, T1, OC3, Fiber, Copper, WAP, Wifi, etc...
None of which helps you here because the final output of all of those systems is digital. Not analog. Problem only comes up if you attempt to convert those digital samples to analog which we don't do in communication (sans dial-up and stuff like that). And try to listen to them.
