What could be causing this spike at 60Hz?

[FargateOne]

So is the issue fixed now with the current sound setting?

This is certainly a bizarre issue, but as others have alluded to, a 60Hz spike could be caused by any number of electrical items on that same circuit. Possibly something trivial that you wouldn't think about.

All I know is the new mic solved the spike appeared all of a suddden without any reason with the old one. (Iremind that the peak appered even with the laptop outside by night in a quiete neighberhood) But I am cursed. The new mic Umik-1 reads all impulses in reverse (all positive satellites are now negative polarity and sub negative are now positive polarity....shi....I think I will ask for a replacement becaus I don't think that Dirac DLBC will like it (even if all is in reverse)

What?!?! Now THAT's weird!

You're not in a boat floating around in the Bermuda Triangle, are you?

May need to throw everything out, move to a new neighborhood, and start fresh.

I’ve been in your situation, @FargateOne… not this same exact one, obviously, but it’s never fun when a process like this keeps backfiring. Super easy to watch the hours tick by while you trouble shoot

After reading posts of members here and elsewhere saying that they he had new Umik-1 and new Umik-2 reversing impulses in their system I decided:
1- keep the Lenovo laptop with Win11
2-return the new Umik-1 to retailor
3- replace it by Umik-2 and will keep it even if it reverses impulses, I won't be happy but at least I will have more accurate timing and delays for DLBC due to the internal clock.

@Sonnie Parker ..my wife suggested that we move in a galaxy far far away witth Eewoks...an no more HT...
