Why is your iPhone 7 Plus speaker keep popping noises or not working as expected? 

When it comes to speaker problems, most people would think that the hardware is to blame. But in contrary, majority of the depicted symptoms are software-related. The program that is responsible for audio outputs might be glitching, thus producing poor sound quality, intermittent or not audible sound.

Technically, the software instructs the hardware to do its function. If the software gets corrupted, then most likely the hardware gets affected. The same concept applies to the iPhone 7 Plus speaker. When the program tasked to command the iPhone’s stereo speakers is malfunctioning, speaker problems like popping noises would instigate. Software problems can happen randomly at any time.

Some issues with the speaker are isolated to an app. For example, when an app crashes, gets corrupted or experiencing audio malfunctions.

There are also other cases where the hardware is to blame for poor quality sound produced by the iPhone 7 Plus stereo speakers. This is likely the case when you accidentally dropped the phone and that has resulted to the speaker being damaged. The built-in speaker is located at the bottom of your iPhone, making it more susceptible to damages from a fall. The speaker may stop working completely or stars to produce static noises if damage occurs to the very thin piece of material that produces sound waves.

To ensure that the problem is not isolate to a certain app, try to test other apps on your iPhone that has sound effects or music. Adjust the volume settings for the app if necessary. If the sound is working fine on other sound apps, then it denotes that the built-in speakers on your iPhone are working and that the problem is isolated to an application.

Step 3. Reset your iPhone settings.

If the speaker problem occurs after making some changes to your iPhone settings, try to revert the settings back to its previous configuration or reset your iPhone settings instead. You can consider the latter option if you’re not sure of which settings to revert.

As the name suggests, the process will reset all the settings on your iPhone to their default settings. Only the system settings will be reset, which means that no data or media will be deleted. Here’s how to reset all settings on your iPhone 7 Plus:

  • Go to Settings-> General-> Reset All Settings.

Wait until the reset is finished.

In case you forget the passcode, you can reset your iPhone settings via iTunes instead. In this case you will need to connect your iPhone to a computer that runs the latest version of iTunes and then follow the onscreen instructions to restore your iPhone 7 Plus to its factory settings. Be sure to note though that the iTunes restore process will erase all of your media and other iPhone data. Thus, creating a backup of your iPhone is necessary before you start.

This method is most likely able to fix the problem caused by software glitches or random app malfunctions that could not be remedied by the usual iPhone reboot or soft reset.

  • Clean the iPhone speaker – The speaker sound quality can also become poor or noisy especially if the speaker is covered with debris, dirt or dust. If necessary, clean the iPhone speaker.

You might as well consider the possibility of hardware damage at this point.
