It's my first time to use AMD platform. I built and have been using the PC for a month. There's a problems bothering me. It seems to be a common issue, but I can't the solution.

1. When I set the PCIe generation to auto/gen4 in Bios/ Advance/ AMD PBS, the audio crackles from time to time.
When I set the PCie generation to gen3, everything works fine.
2. I bought two additional gen 4 riser cables. But the issue remains the same.
3. If I set the PCIe generation to gen3, will I lose the performance of my Gen 4 NVME SSD.
