Need help on my Mac Mini M2 Pro Static noise from external Audio Speakers

Recently I bought a Mac Mini M2 Pro. I have connected the Logitech Z625 THX Speaker using Aux Cable. When the Mac Mini is in Idle there is an annoying static sound coming from the speakers. I have tried replacing the Aux Cable, using RCA to Aux cable, Noise suppression/isolator, fixing Ferrite Core Noise Suppressor Filter Ring Cable Clamp RFI EMI on the power cable and aux cable, and even changing to another speaker still getting the annoying static sound.

Mac mini (M2 Pro, 2023)

Just got back my Mac Mini M2 Pro from the service centre last Thursday and was testing out for the past few days. The Static noise is no longer there for now. I was informed by Apple Support that they have replaced a new motherboard.

Well, that's good and bad.

It eliminates the speakers as being the problem and it implicates the mini.

If you have any other devices connected to the mini, I'd advise disconnecting everything but the speakers, kbd, mouse and monitor and evaluate. Maybe another device is causing the issue, actually maybe even the monitor. If the problem remains, relocate the Mac to another room and reevaluate. Perhaps there's something in the environment that is causing radio interference.

If that still fails to resolve the problem then I'd say the mini is due for an evaluation by a service tech, either at an Apple Store or an authorized service provider.

Give the speakers a run on another computer and see if the noise remains.

Otherwise, return or exchange the speakers. Maybe they are defective.

I have checked everything as per your guide and found the problem still persisting. So have decided to send the Mac Mini to the Service Centre to check since it's still under warranty.

I have connected the same LG 29" 29WQ600 IPS HDR10 monitor and Logitech Z650 THX external speakers to my Macbook Air M2. Been connected + using it for the past 12hrs and did not face the same problem with my Macbook Air M2.

I believe my Mac Mini M2 Pro is the 1 having the issue.
