Sound from a GPU coil whine in headphones.
Hello everyone. Have you ever experienced unusual issues where the GPU makes a whine in your headphones? Recently switched from Intel to Ryzen, installed a new motherboard and CPU, but everything else remains unchanged. Now, when I wear my headphones while browsing, strange sounds appear, especially when opening tabs or when the GPU is under load. The movement on the screen seems to produce noise through the headphones. I’ve read about this before and think it might be related to EMI (electromagnetic interference). Is there a solution to fix this? My previous motherboard was solid, and the audio quality hasn’t been great compared to before. My current setup includes a Gigabyte B450 Aorus Elite v2 CPU with Ryzen 5 5600, an old Gigabyte Z370 Aorus Ultra Gaming 2.0 CPU with I3-8350K GPU, 1070 Ti RAM, Corsair PSU 550W AIO cooler, and M.2 SSD. Please note, a friend suggested it could be the onboard sound card picking up power from the PCIe connector because of proximity. The motherboard isn’t cheap. If I take it to warranty, I’d have to wait months and there’s no guarantee they’ll say everything is fine. Sorry for any confusion with my English. Thanks.
Seems similar to problems with aging vehicles and engine load noise. An online resistor often resolves the concern. (Removed the annoying whine from a 2008 Toyota RAV4) This should help: https://www.amazon.com/JABINCO-Ground-Lo...1417&psc=1
The issue stems from electromagnetic interference entering the audio section of the motherboard through the graphics card, and the isolation isn't working well. It seems the problem lies in the board's design and how audio is separated from other components. If you send it back via RMA, Gigabyte's team will check if it meets their standards. They might suggest returning the board or fixing it yourself with an external DAC or the method proposed by @BiotechBen. Updated April 23, 2023 by Godlygamer23
You're right, as your friend mentioned, the motherboard design matters a lot. Considering that, a PCIe sound card could definitely improve the audio experience. It would likely be noisier and offer higher quality sound.
