Running an NVIDIA RTX 3090 FE in my GIGABYTE X570 Aorus Ultra with PCIe gen 4.0, I get audio crackling from the integrated audio chipset and USB (mouse, webcam) glitches/stutters/resets. This happens under certain loads, especially when screen capturing from different applications like TechSmith Camtasia and Microsoft Teams. If I set the PCIe to gen 3.0 in the BIOS, everything seems fine (except my NVME can't run at full speed). I upgraded from an NVIDIA RTX 2080 Ti FE (PCIe gen 3.0) to the RTX 3090 and the issues started. This might not be isolated to RTX 3000 series cards or Gigabyte motherboards, as some AMD GPU and other motherboard users have reported similar issues. The commonality seems to be AMD CPUs with peripherals running PCIe gen 4.0.
My system details:
What I have tried so far:
Any suggestions would be appreciated.
A high frequency EMI from PCIe somehow affect your audio, or this is some elaborate driver/bios bug. Either way there's no fix beside using pcie 3.0 or external DAC. You might RMA your board if you want.
It ends up that an increasing number of people are reporting this issue, across a variety of motherboards, with both AMD and NVIDIA GPUs. The only commonality so far is PCIe Gen 4.0, AMD CPU, and AMD chipset. My guess is there's some form of a voltage management issue with AGESA/BIOS.
You have literally the exact same issue as me. At first I thought it was my sound blaster since tons of people are complaining about the same on the sound blaster subreddit, but I dug further and it even happens with onboard sound! I don't have issues with USB devices when running on PCI-E 4, only sound issues, but my buddy has the sound issues AND USB issues on PCI-E 4.
We should be screaming about this, it's been going on for what looks to be the beginning, but just no one had PCI-E 4 GPUs to test it.
I tend to agree that this issue has been there for a long time. As I search older posts, I see similar symptoms being reported. Hopefully, it's an issue that a BIOS update or chipset driver update can resolve. One website had a post about it being a known issue and AMD will resolve in a future set of chipset drivers.
It REALLY feels like a voltage problem, but I'm not brave enough to up the voltage on the SoC... all I know is I try the DPC latency monitor and it says everything is 100% fine, all while I hear popping on my headphones.
I hope they can fix it soon, running PCI-E 3 is gonna hurt when nVidia IO comes out, because that'll likely hugely benefit from PCI-E 4 speed.
Gigabyte released BIOS F31J for X570 Aorus, and it includes an update to AGESA. I am seeing improvement with this BIOS update (but not full issue resolution). If you're running a Gigabyte X570 Aorus, this is worth testing.
