iPhone is a great smartphone for all types of consumers. However, like all things in this world, it is not eternal. And since smartphones see a lot of use day after day, some parts are bound to break down with wear and tear. Since the sound system is the most used part of the phone, it stands to reason that it is also the issue that is most popular with Apple repair companies or iPhone repair DIY gurus. Some sound issues might be serious enough to warrant a visit to an iPhone repair specialist. Others might be solved by a simple Apple repair job at home. Either way, when having issues with sound, first thing you should do is try to diagnose what’s wrong, and then follow with doing a home iPhone repair if the issue is easy to solve, or visit an Apple repair company so their specialists do it for you.
Here’s the list of the most common signs that mean you need to do an iPhone repair or take your phone to an Apple repair company:
You don’t have system sounds.
This means that when someone calls you, you hear the phone ring. The ring and messaging signals work just fine. Sounds can play fine when you go into the settings menu, too. When you are just using the OS, however, sounds such as lock/unlock sounds, system notifications, or keyboard tap sounds won’t work.

You don’t have alerts.
This is a reverse of the previous issue. System sounds work fine. Alerts such as messaging or phone signals, however, don’t work.
You don’t have any sound.
Obviously the worst, it does what it says. Your iPhone is completely mute. This muteness can be a constant or sporadic curse, but it’s total.
So, how to fix these issues? Well, aside from taking your phone to an Apple repair company, the safest bet would be to do a DFU restore. DFU is short for a Device Firmware Upgrade, and it can solve issues with software. If that didn’t help, you most likely have a hardware issue. If so, it’s best to take your phone to an iPhone repair company, as you risk damaging it further if a DIY repair effort is mounted.
If you’re ready to risk it, however, there are several things you can try to do to save your iPhone. The most counterintuitive of them is to replace the dock connector. Strangely enough, in most cases replacing the dock connector is enough to fix any sound issues. That is because the dock connector has a lot of wiring and components that are responsible for delegating sound through the iPhone. If that didn’t help, you should take a look at either the actual loudspeaker, or other sound components.
If you having issues with sound, try using a DFU restore. If that didn’t help, you probably have hardware issues, and the best way to do your iPhonerepair http://applerepairmtl.com/iphone/?lang=en is to take it to a good Apple repair http://applerepairmtl.com/reparations/?lang=en company.
