Normaly The signal comming from the computer audio jack should not have any noise.
But when i connect the signal to my oscilloscope i see a lot of noise in the signal.
How to solve this ?
Computers' built-in sound devices are notoriously cheap & cheerful... & noisy.
The only real 'fix' would be to invest in a reputable outboard device, connected over USB.
Required, but never shown
