iPhone 6s Distorted Sound

I Have the same issue, distorted sound whenever I turn loud speakers on

Craig and others, I kept my appointment at the Apple Store today. They listened to my iPhone and heard the distortion. They immediately replaced my phone and I walked out within a couple of minutes. My new iPhone 6s does not have any sound problems. So it must have been a hardware issue. Glad I got this worked out. Jeff (iPhone 6s, iOS 9.0.2)

i think i am going to get the replacement and see if it works or not. I hope it doesnt have any other problem.

Let us know... if it's hardware hum.... We all have to get replacement till the speaker works fine... This gonna be fun... 😟

Just talk to them at the Apple Store and let them test your iPhone. There are so many reasons for sound distortion that yours may not really be a problem that will be fixed by replacing it. The distortion I was experiencing was actually not that bad after the updates to iOS were installed, but I exchanged it anyway. Hopefully the distortion will not return, but if it does I will just live with it since it actually was not very noticeable unless you are listening for it. After reflection, it is hard to say if mine was for sure hardware. Let them run their diagnostics and see what they think.

Just updated to iOS 9.1 beta 4 and I still have the annoying distortion at the end of the swoosh after a couple of text messages. Everything else sounds fine except for that text message send and receive notification. I've never experienced ringtone or other notification distortions. I guess I'll try a couple more updates before I visit the Genius Bar.

My appointment was advanced to yesterday morning. Three people behind the genius bar did not hear the distortion that I heard and they also ran diagnostics. They said the phone was fine. I hear it less when the phone is not cranked up to the highest volume level. They did not exchange my phone but did keep notes regarding my visit. Do I need to ask for an exchange??

I had the same issues with the message sent SFX sounding distorted and loud along with my lock screen sound. Oddly enough, I was able to fix all cases by going into Settings > Music and toggling off and back on the Sound Check option (mine was on by default or from the previous backup) at the bottom of the screen.

So glad to find this thread because I have been driving myself crazy with noticing this distortion!

I can tell you it is not due to backups because my iPhone 6S is brand new first hand and I did not load a backup to my device. I have noticed the issue while sending iMessages. The swoosh sound effect while sending is slightly distorted.

I am very surprised I noticed that as being my issue, because after reading the original post and trying the "Opening" ringtone on MAX, I definitely noticed the speaker / audio quality issue is REAL!

The nearest appointment time at my local mall is October 12th unfortunately, so I will be definitely getting my device swapped!

HI,

news from this "Speaker Gate"...

1) Restart the iPhone

2) uncheck and chek the sound volume equ in music menu. (The laSt one)

3) charge the iPhone to 100%

and... Try your music, ringtone or video....

The distortion is gone.

for people who changed their iPhone, i think they picked iPhone fully charged... so no distortion.

Are you saying to turn on "Sound check" option and then charge to 100%?

Yes !

For some reason, the problem disappears at 100% and around...

There is a simple way to be sure whether it's a hardware or software issue. It will confirm that without a single doubt.

Plug your iPhone to your Mac, then launch QuickTime, screen record your iPhone with the audio from it.

Go to the message app, and send a message. If you hear it distorted on your phone, but good on the screen record, then you have your answer 😉

Its intermittent so it appears. I think it's hardware related due to fixing over 2,000 Apple laptops in my experience. Someone try it and find out. I'm busy at work.
