I'm experiencing some strange problem with audio coming from my RaspberryPi 4.
I'm not able to understand if it is something related to hardware (audio connection) or to the software.
In a few words audio is glitching/stuttering/digitally clicking don't know ho to better describing it.
Please find attached a recording I've made from a pair o headphones connected to the audio jack output of the pi
The problem is not always present: sometimes it start since booting the pi, other time it suddenly appears after some time the pi is running, some other time, from being present, the audio problem disappears without any reason.
The problem is there even if I lower the audio volume from the GUI (audio icon on the upper right corner).
The Pi is powered by its official power supply adapter. It is connected (via HDMI 0 port) to a HDMI monitor.
Audio is forced to the Jack output (via raspi-config).
Have you ever faced something similar?
How can I better debug it?
How can I solve?
Thank you so much for your support.
