This can happen on older hardware or with very high-bitrate files. You can try reducing the audio queue size in the Audio Switcher settings, though usually, simply lowering the speed slightly (e.g., from 1.5x to 1.3x) resolves the issue.

Check the box that says (sometimes labeled as "Use built-in audio renderer time-stretcher"). Click Apply and then OK to save your settings. Method 2: Configure the Sanear Audio Renderer (Alternative)
The native pitch-preserving speed control in MPC-HC is one of its most powerful hidden features. While it has some quirks—like occasional audio clipping or desync issues—simply switching from the default output to the "MPC Audio Renderer" transforms your experience, allowing you to consume content at your own pace without the dreaded chipmunk effect.
