If you have an iPhone 7 or 7 Plus with a grayed out speakerphone icon, or other varied audio issues, you may want to look into [link|https://www.ifixit.com/News/32783/how-to-fix-a-grayed-out-speaker-icon-on-the-iphone-7-or-7-plus|iPhone 7 Audio IC issues.] | |
+ | == The Basics == |
+ | |
+ | Before giving any of the more in depth fixes a try, start with these common quickies. |
+ | |
+ | * Verify that the Silent/Ringer toggle switch, is set to ring (***hint: silent is orange***). The position of this switch overrides all other ringer settings. |
+ | * Restart your iPhone. |
+ | * Remove any accessories (cases especially) that could be obstructing the speaker. |

- | == Sound Settings |
+ | == Misconfigured Sound Settings == |
Although “sound” on an iPhone seems simple, it is actually a conglomeration of several different settings. Each audio related function in the phone has its own correlated setting (ie. phone call, media, ringer, etc…). | |
- | * Verify that the Silent/Ringer toggle switch, is set to ring (***hint: silent is orange***). The position of this switch overrides all other ringer settings. |
* Is Do Not Disturb on? This would also override volume settings for incoming communications. On newer versions of iOS, Do Not Disturb has been replaced by Focus. | |
* Check that the volume level for the sound setting you're missing is set to the expected level. Volume controls are context sensitive and adjust the volume for the current function. For a quick look at the current volume level, use [link|https://support.apple.com/en-us/HT202769|Control Center]. | |
iPhones, like all computerized devices, can be subject to software defects or bugs. The phone may have encountered an error, a third party app is wreaking havoc, or the OS itself may have become damaged. | |
- | * Restart the device. This can relieve some hang up in the boot process. |
- | * If you’re encountering the issue only in a specific app, see if that app has any updates. App updates can be found by navigating to the App Store and clicking the account button in the top right corner. |
- | * iOS itself may also need an update. In the Settings menu, under General, there is a selection for Software updates. |
+ | * If you’re encountering the issue only in a specific app, see if that app has any updates. App updates can be found in the Google Play Store by selecting your account avatar in the upper right corner, then selecting Manage apps & device. |
+ | * Android itself may also need an update. In the Settings menu, under General, there is a selection for Software updates. |
** Before processing an update, you may want to back up your device, in the case that something goes awry. | |
* Perform a factory reset. In the case of potentially faulty software, it is recommended to try the [link|https://support.apple.com/en-us/HT201252|reset via a PC with iTunes or a Mac]. This installs a fresh copy from Apple rather than reinstalling from your device. | |
* If all else fails, replace the jack. This part is generally a included in the charge port/dock assembly. See [[Topic:iPhone|the list of iPhone Guides|new_window=true]] to find out how to do this repair on your device! | |
- | == Speaker |
+ | == Speaker Failure == |
It stands to reason that if you're still not getting sound, it's because the part that produces audio just doesn't work. | |
== Damage to Connecting Hardware == | |
- | Both the receiver speaker and loudspeaker lack direct connections to the logic board in most iPhones. They typically have contacts which interface with the front facing camera assembly or the dock/charging flex cable, depending on the speaker in question. Signals for the speakers would be transmitted through their respective cables. If these cables are damaged, it will prevent audio signals from getting to their destination. |

* Check for any signs of liquid, corrosion or damage to the cables in question. Even a small nick or tear in a cable can cause a break in an electrical line. Replace if damage is located. | |
* Check the connector ends as well as the cables themselves. Bent pins, or damage to the connectors can also mean lack of data transmission. | |
- | * If your damage is a result of liquid entry, cleaning up minor corrosion can be done with some isopropyl alcohol and gentle scrubbing with a toothbrush or cotton swab. This should not be considered a permanent solution, since corrosion will oxidize the surface of the metal contacts, decreasing electrical conductivity and compromising the integrity of solder joints, but it can restore functionality if you’re looking for a quick fix. |

+ | == Logic Board Fault == |
Ultimately the board is responsible for processing all of the audio signals going out to the speakers. If the board hardware is not working properly, signals may not be sent to the speakers to begin with. |
