The click at about 3 seconds in sounds like a old clock? is this click from the unit? Internal clock harmonic?
I had noise from a SM-PSU that was for an external HDD, but not what I hear on your recording, strange noise
Maybe to try and eliminate if it is an internal fault with unit or a combination of being connected in a new system, may I suggest to try unplugging all unnecessary SM-PSU's?
Look forward to your reply
