Hello everyone, I apologize if the topic is off topic. Rocksmith doesn't work for me on my PC and I'm completely desperate. I have the official cable, it is detected on the PC and there is sound. I installed and checked all sorts of forums and fixes. This also did not help. Can anyone please write to me in discord(ultrago0se) or here how to solve the problem with Rocksmtih not seeing my cable and guitar in particular (everything works on PlayStation, but there are really not enough custom songs)

What operating system? If Windows 10 you might need to give rocksmith permission to use the microphone. The RS cable appears to Windows as a microphone device. To do this open the "PC Settings" app, Click on Privacy. Click on Microphone down the left hand side. Make sure "Microphone access for this device" is ON, Make sure "Allow apps to access the microphone" is ON and make sure "Allow desktop apps to access the microphone" is on. You might need to scroll down to see that last one.

If your cable is working and makes noise without Rocksmith then this is probably what's wrong.
