I know this thread is a decade old, but I found it in my quest to solve the same problem: any time I'd render in Resolve my speakers would buzz with pink/white noise. I marked this thread and continued on my quest until I found my answer: I needed balanced audio cables to the speakers.
Now, I don't know if OP was using external speakers and if so, how they were hooked up, but to anyone who finds this thread in the future, I wanted to post a possible resolution.
My setup:
- Windows 11, 32GB RAM
- Ryzen 5700G (not using onboard graphics)
- NVIDIA GeForce RTX 3060 TI
- Focusrite Scarlett 18i20 connected via USB
- Monster Power Pro 9000 PowerCenter
- Seasonic Focus GM-550, 550W 80+ Gold Power supply
- KRK Rokit monitors
The monitors were connected via 15' unbalanced 1/4" TS cables. I would notice a light hum/buzz at various times, not just when using Resolve, and before my tinnitus was bad, I could hear them start to hum when I turned my monitor on. I swapped the cable out for 15' Balanced TRS 1/4" cables and all noise disappeared.
To understand why, read up on the difference between balanced and unbalanced cables.
