Just today my Blue Yeti has started putting out what was described to me as on TS and Discord as "alien robot sounds". When monitoring it through its 3.5 mm jack, I don't hear it, but I have been hearing a high-pitched whine when there's no other sound coming through for some time now.
The sound occurs when listening to the device through the Windows sound settings, in VoiceMeeter and is transmitted in all VoIP apps I've tried. I have no other machine to test with.

Tried: different USB cable, different USB port, unplugging neighbouring devices, restarting PC.
I'm not very audio-savvy, but I'll try to provide what I can if we can fix it.
