I have a relatively similar problem.
Bought a new Asus Z490 motherboard + I7 10700k and since then I have problems with my audio. Theres is a high ringing+crackling noise round about 6000 Hz. This happens while im moving the volume slider of Windows and also the Html5-player. While using Spotify there isn't this problem with the volumeslider. That is very strange.
What I've done so far:
- reinstalled Windows 10 (2004)
- no overclocking- all hardware drivers and the bios are uptodate
- tested different soundcards and drivers (cleaned all drivers/software before reinstalling new ones):
- Realtek ALC S1200A onboard sound
- Asus Xonar D2X
- Sound BlasterX AE-5
- Asus Essence STX II
- Steiberg UR-22 external DAC (connected through Usb)
- also switched the following hardware:
- Ram
- Power supply
- checked the latencies with LatencyMon -> result: no issues
- set different bitrates from 16bit to 24bit and from 16000 Hz to 192000 Hz
- all software modulations are off
Maybe there's an issue with some codec transformation. But from my point of view I think it's an windows bug. I don't know what else to do.
