No Sound on iPhone
When there is No Sound on iPhone, you will not hear ringtones, alarms, music or any other sound coming out from the speakers of your iPhone.
When this happens, it is natural to think in terms of the speakers being damaged or something else being wrong with your iPhone.

You will find below some of the methods that have worked for other iPhone users in fixing the problem of ‘No Sound on iPhone’.
1. Check Silent Mode and Volume Buttons
It is quite possible that you or someone else with access to your device may have accidentally placed your iPhone in Silent Mode or moved the volume button all the way back.
Hence, take a good look at the Silent Mode switch and Volume buttons on your iPhone.
Make sure that your iPhone is not placed in Silent Mode and the Volume is not set to its lowest level.
2. Restart iPhone
If the problem of No Sound on iPhone is due to stuck programs, restarting iPhone can fix the problem by terminating stuck programs.

2. Power OFF iPhone by dragging the slider to the right.
3. Wait for 30 seconds and Restart iPhone by pressing the Power button.
3. Inspect Headphone Jack
Use a Flashlight to inspect the headphone jack on your iPhone for accumulation of lint/debris.
1. Use a toothpick to clean the Lint/Debris as gently as you can. Blowing with your mouth might work if the stuck particles are small.
If you notice signs of moisture, try to gently blow the moisture out using a hair dryer or simply wait for the moisture to dry out.
2. Clean the Speaker Port and Receiver Mesh using a soft brush.
Note: Make sure that you are using a soft brush and avoid causing damaging to your iPhone.
4. Check If iPhone is Stuck in Headphone Mode
Sometimes, iPhone can remain or get stuck in headphone mode, even when the headphones are not plugged-in.
1. Make sure headphones are not attached to your iPhone.
2. Use the Volume Up and Volume Down buttons on your iPhone and watch the Volume indicator that appears on the screen of your iPhone.
If iPhone is stuck in Headphone mode, you will see ‘Headphone Icon’ on the Volume indicator.
A quick way to get iPhone out of Headphone mode is to insert Headphones into the Headphone jack of your iPhone and remove them. Repeat this step 4 to 5 times.
The idea is to make your iPhone sense the action of headphone insertion/removal and to dislodge grime (if any) in the headphone Jack.

The Volume buttons on your iPhone control the ‘Ringer’ Volume when you are on the Home Screen and ‘Volume in Apps’ while you are using the App.

Close the App > Go to the Home screen and use the Volume buttons to increase or adjust the volume on your device.
