Small crackling sound when it comes out #6

Hi, Thank you for this tuto which works very well. However I have a small crackling sound that appears, only when the sound comes out (if I raise my arm, no crackling sound). Do you have an idea? Could it be due to the hardware or the configuration?

What do you mean with 'crackling sound'? Can you maybe make a video recording of this?

For me it's not the cable that's to blame as I've tested another way of doing it ( via AirPlay where the turntable is plugged directly into my phone or computer ) and it works perfectly. My network is also good as I am wired. I think either my raspberry has a problem but I don't think it needs a lot of power or a problem with the settings but I followed the tutorial

Interesting. It sounds like the regular vinyl crackling, but it definitely is not that, as I'm pretty sure this is static (electric) noise, not mechanical. Do you by any chance have your turntable grounded?

actually my turntable is not connected to the ground in this configuration (I mean with the raspberry instead of my amp) I will try to connect it to the ground ;) for info my turntable is the Audio-Technica AT-LP120XUSB
