How to Fix a Crackling Audio on Your MacBook?

Solving Crackling Audio Issues on MacBook: Crackling or distorted sound from MacBook speakers could spoil the whole experience. Crackling audio typically originates from software bugs, outdated drivers, or a hardware conflict. The good news is that most of these common problems are easy to fix. Below is a quick set of steps to troubleshoot and fix crackling audio on any MacBook model

Restart Your MacBook First: Go for the easiest fix first: restart the MacBook. It refreshes the system and clears away temporary glitches. If the crackling sound was due to a minor software hiccup, then all it would take is a quick restart to repair it. Always try this one first before resorting to the more extensive fixes

Check Audio Settings and Output Device: Go to System Settings > Sound and check your output device. If the wrong speakers or headphones are selected, it could cause crackling. Also, ensure that the output volume is balanced and is not at the maximum. Switch devices to test whether the issue persists across all outputs

Reset The Core Audio Process: Resetting Core Audio can be a solution for several potential sound issues. Open Terminal and type: sudo killall coreaudiod, then press Enter. This causes the audio driver to restart; the sound will momentarily go off and then come back. It is safe and often helps to clear distortion or crackling sounds

Update macOS and Apps: Sometimes, crackling is the result of software bugs. Go to System Settings > General > Software Update, then install all available updates. Also, update any audio-related apps. Usually, newer versions of macOS fix audio driver issues. Mighty best way to ensure smooth working is always to keep updated

Look for Bluetooth Interference: Using a pair of Bluetooth earphones? Disconnect them and try the internal speakers. Often, Bluetooth connections can create interference with the output audio or cause crackling due to a low battery or outdated firmware. Try unpairing and then pairing again, or connect wirelessly to check for the difference

Still Crackling? Try Resetting Your PRAM or SMC: When nothing else works, try resetting your MacBook's PRAM (Parameter Random Access Memory) or SMC (System Management Controller), as they manage audio and hardware settings. Open Apple's support guide, matching your Mac model, to complete your reset safely. Otherwise, if the problem persists, it may be related to hardware; thus, you should have it inspected at an Apple Store
