FaceTime calls cracking audio

Hi aarav37,

Try testing the issue in safe mode. This will start up your Mac so that it performs certain checks and prevents some software from automatically loading or opening, which could help narrow down the cause of the issue. This article will walk you through the steps: How to use safe mode on your Mac

Apple silicon

1. Shut down your Mac.

2. Turn on your Mac and continue to press and hold the power button until you see the startup options window.

3. Select your startup disk, then press and hold the Shift key while clicking “Continue in Safe Mode.”

4. Log in to your Mac. You might be asked to log in again.

Intel processor

1. Turn on or restart your Mac, then immediately press and hold the Shift key as your Mac starts up.

2. Release the key when you see the login window, then log in to your Mac. 

3. You might be asked to log in again. On either the first or second login window, you should see ”Safe Boot” in the upper-right corner of the window.

Regards.

Hello aarav37,

Thanks for testing that. If FaceTime continues to fail in safe mode, that gives us some good information. Let's see if this behavior persists in a second user account on your Mac. Testing in a new user account will help determine if the issue is system-wide or user account-specific.

Please follow these steps to make a test account that can be deleted later: Change Users & Groups settings on Mac - Apple Support. Follow this guidance to make that second account:

Add account - Create a new user or group.

Click the New Account pop-up menu (you may be asked to enter your password), then choose a type of account.

* Administrator: An administrator can add and manage other users, install apps, and change settings. The new user you create when you first set up your Mac is an administrator. Your Mac can have multiple administrators. You can create new ones, and convert standard users to administrators. Don’t set up automatic login for an administrator. If you do, someone could simply restart your Mac and gain access with administrator privileges. To keep your Mac secure, don’t share administrator names and passwords.

Once you've got that account made, please test this behavior and let us know if the issue persists. Thanks and take care.
