pc audio crackle

PC audio crackle often stems from aggressive CPU power management rather than faulty hardware or drivers. Disabling deep C-states in the UEFI or BIOS can resolve random crackling by preventing the processor from entering low-power states that disrupt low-latency audio playback. This firmware-level adjustment ensures the CPU remains responsive during audio tasks, eliminating timing glitches that cause crackle. The fix applies to gaming, streaming, and production workloads where consistent audio timing is critical. Users should check their motherboard manual for C-state settings and disable options like C6, C7, or C10 to stabilize audio output.
