Sound from the motherboard is audible.
The motherboard seems to produce an electrical noise that becomes more pronounced when amplified. At startup, it starts as a crackling sound and evolves into a consistent hum. While it’s loud through the audio output, it remains audible via the input channel, particularly during voice recordings. Despite troubleshooting, the issue persists—testing with different power supplies and grounding methods didn’t eliminate the noise. It appears to be related to the power supply or the board itself. Anyone have any suggestions?
It’s likely caused by VRM interference (EMI). The sound amplification you see is probably from mismatched electrical voltages between your PC and the speaker. To fix it without replacing parts, consider using starquad cables first. This may only reduce the hum or add some clicking sounds instead of a complete solution. For a precise fix, you should note the exact hardware and connections you’re using.
