Hi htere

Please try this

. Adjust Software and Audio Settings

• Turn off EQ and Audio Enhancements: Go to Settings > Music > EQ and turn it Off. 
• Reset Audio Balance & Mono Audio: Go to Settings > Accessibility > Audio & Visual, ensure Mono Audio is off, and verify the left/right balance slider is centered. 
• Disable Keyboard Feedback Haptics: Go to Settings > Sounds & Haptics > Keyboard Feedbackand turn off sound to prevent amplifier spikes. 
• Update iOS: Make sure you are running the latest software update via Settings > General > Software Update, in case Apple releases firmware refinements for audio routing. 

2. Check Physical Factors

• Remove Cases or Screen Protectors: Heavy-duty cases or misaligned screen/speaker films can vibrate against the speaker grills or muffle output, causing distortion. 
• Clean the Grills: Gently brush the speaker openings with a clean, dry, soft-bristled brush to clear out pocket lint or dust. Avoid compressed air directly or sharply into the ports. 
• Test Charging State: Notice if the crackling happens only while plugged into a wired charger (due to electrical noise from the power delivery) or if it persists on battery power.
