Truthear Crinacle Zero background white noise with apple dongle on pc

[Frost_]

I recently got a Truthear x Crinacle Zero, and the sound seemed too low. So I got the apple type c to 3.5mm dongle and connected it to my USB-3.1 port via the type c to USB-A converter. The sound volume problem has been resolved, but I can hear a background white noise, which is not much but easily noticeable. It gets almost unnoticeable when I reduce the volume to 70% in any scenario.
I hear the noise:

• when my Windows system sound is being played
• When I play specific songs, but harder to notice in other songs or when many instruments are playing simultaneously.
• When I hover my mouse over the menu in Valorant.

I can't hear it when I am in an actual match in Valorant, and it's a bit harder to notice in films.

I tried the dongle on my phone Samsung galaxy m21. I can still hear the white noise when the volume is at max, but I thought maybe it would work better with the dongle connected to the PC. There is no white noise when I connect my IEM directly to the motherboard 3.5mm port. I tried using different USB ports didnt work. Someone said I should change the sample rate, but it's locked at DVD quality and greyed out, so I can't change the sample rate.

Is my dongle not working properly, or is it normal to hear the white noise at high volume?

Try different USB ports to avoid interference. It's the easiest way to minimize or get rid of it. I had the exact same combo last week, and on a good USB port it has a nice, quiet noise floor.
