You should now hear the video sound without any problem.

3. Disconnect Bluetooth Devices.

When an iPhone is connected to any Bluetooth device, it does not emit any sound from its speakers. So, if you cannot hear video sounds, ensure that no device is connected via your iPhone’s Bluetooth.

To do so, follow these steps:

  1. Launch Settings from your iPhone. 
  2. After that, tap on Bluetooth
  3. Turn off the toggle for Bluetooth

Now, try playing a video, and the sound should be working fine now. 

4. Remove External Devices.

If there is any external device attached to your iPhone, it can interfere with the video’s audio or your iPhone’s speakers, resulting in no video sound. Ensure no external device, such as a microphone, Bluetooth, etc., is connected to your iPhone for effective video playbacks.

5. Remove the Case.

Sometimes, the device case interferes with the Ringer or volume buttons causing the volume to go down or accidentally enabling Silent mode. The case may also block the microphone, which results in the recording of muffled noises in a video.

Therefore, removing the case will eliminate all these issues and allow for effective audio recording and video playback with proper volume.

6. Clean the Mic and Speakers.

If the video sound is not working on your iPhone due to a problem with the mic or speakers, then cleaning them will likely solve the issue. That is because your device collects dirt and dust particles over the years, which can block the microphone or speaker holes.
