My playbacks (audio) stutter whenever I use Bluetooth devices. This happens on iPhone 11 Pro Max, iOS 13. The sound looks static whenever this happens and does not flow as it should. Previously, I had same setup on iPhone XS on iOS 13 and everything worked fine. Where is the bug hiding?
Might try to force restart the iPhone to give it a refresh, I’m also an iPhone XS Max user, and I occurred once, if that doesn’t solve anything then best bet is to check with AppleCare for possible hardware malfunction.
Launch the Settings app and go to Bluetooth.
Tap on the “i” icon against the device name you’re having problems connecting.
Tap on the “Forget This Device” button and confirm your action.
Now pair your iPhone with the device again, and see if the issue has been solved.
