Unable to hear sound in screen recording on my iPhone

If you mean your screen recording have no sound as in your sound, then that would mean the microphone was turned off during the screen recording. Next time before you start another screen recording, hold on the control in the Control Center then tap Microphone to turn on.

The issue you're experiencing with no sound in your screen recordings, except for Snapchat, could be due to:

1. Microphone Not Enabled:

• When starting a screen recording, ensure the microphone is turned on.
• Open the Control Center, long-press the Screen Recording button, and tap the microphone icon to enable it (it should turn red).

2. Audio Source Conflicts:

• If your iPhone is connected to Bluetooth devices (e.g., headphones or speakers), the audio might not be captured properly. Disconnect Bluetooth devices and try recording again.

Snapchat might work fine because it uses its own recording system, bypassing the iPhone's default screen recording settings.
