About this tag
CPU C-states are power-saving idle states built into modern processors that can reduce power consumption by halting the CPU clock or lowering voltage when the system is not under load. On Windows, aggressive C-state transitions may cause audio crackling, stuttering, or other latency-sensitive issues because the CPU takes too long to wake from deep sleep. This tag covers discussions about disabling or adjusting C-states in UEFI/BIOS settings to improve real-time performance for audio production, gaming, or low-latency workloads. Topics include identifying C-state-related audio problems, comparing C1/C6/C10 states, and balancing power efficiency with responsiveness. The content focuses on practical troubleshooting for Windows users experiencing audio glitches tied to CPU power management.

    Random PC Audio Crackle Fix: Tame CPU C-States for Low-Latency Playback

    Sometimes the fix for random PC audio crackle is not a new DAC, a fresh driver, or a better cable, but a firmware-level CPU power setting that stops the processor from diving into deep sleep states during ordinary Windows use. The uncomfortable lesson is that modern PCs can be fast enough for...
