Crackling noise from iPhone 17 Pro Max speakers

If your iPhone 17 Pro Max speakers crackle only in media apps but pass Apple Diagnostics, it’s almost certainly a software/audio-processing issue in iOS 26.x — especially with Spatial Audio, Dolby Atmos, or EQ processing. Turning off Spatial Audio, resetting audio settings, or disabling certain sound features often fixes it. If the crackling occurs during phone calls or system sounds, visit Apple for a hardware check.

Expressing your crackly feel or conveying auditory experiences effectively through these forums may be challenging. For more personalized and in-depth assistance, I recommend securing a Genius Bar Reservation and exploring the various support options provided by Apple.

Troubleshooting Crackling iPhone:

A. Two Sites to Go By:

• If you Can't Hear a Person on a Call or Voicemail or if the Sound isn't Clear on your iPhone - Apple Support
• If you Hear no Sound or Distorted Sound from your iPhone, iPad, or iPod touch Speaker - Apple Support

B. Await the Updates:

Awaiting the next update is a great idea. So, give it a go, and then see if all is fixed. If not, then I'd pursue getting this serviced.

C. Restore From a Time Machine Backup:

Did you ever create a backup of your Mac prior to this issues installed? If so, restore this iPhone from it. If not, then take this as a learning experience, knowing to always to create a backup, both prior to and after making any major changes to it (i.e. update installs), whatsoever.
