Real Tone Cable, guitar sound cuts off

Good day! Hope this is appropriate for this question :)
Got the game and the Real Tone Cable since 2014, worked fine. And then suddenly — at the start of the game, the sound is there, but if you go to the calibration of the gain, at the moment of "Play louder" the sound at first still there — and then abruptly cuts off.

I tried another guitar, license / pirate, another USB port, another PC — all the same. With NoCableLauncher and with a regular guitar cable plugged into the line input-it works.

Is it the end for the RTCable? :(

It might be that your cable is failing, but doesn't have to be, It might also another program interfering.
Maybe a Windows update. Or update of another program.
Like razor software or hardware can be a problem.
You might check the windows event manager for error messages. Try disconnecting other stuff. Don't use a Bluetooth headset... Try validating files through Steam and what more..?

Hmmm, could that be a caching problem??
Like buffer(data_,max_length)
I remember setting it in the rocksmith ini aswell, and that gave problems. I just leave it at default now.
But it also took some tweaking in my recording software to (cubase)

Sounds like with the steps you took to check other cables/PCs/ports/guitar, it looks like the cable itself. If you can’t get one online, what’s wrong with using the NoCableLauncher and a real cable if the game detects it?

Sound like you've tested all except Real Tone cable.
Easiest way to test is get another Real Tone cable and do swap test as basic of troubleshooting.

Dude, thank you so much for telling me about the NoCableLauncher. My OG cable doesn't work with my new PCs even with USB 2.0 ports. I was able to play through my Behringer USB Mixer with no problem.
