After iOS 7 sound output is unbalanced left/right

On my GSM iPhone 4, after upgrade music output (left/right) is not balanced. How to fix?

There's a slider to adjust the headphone volume balance under Settings > General > Accessibility (in the 'hearing' section).
I had this problem too and it turns out that my earphones, rather than the phone, are at fault. Try with another pair of earphones, if you have one handy.

Why do my sound output settings keep resetting after restart?

Just bought a MBPro with OS 10.6.4.
After restarting my sound output settings keep resetting to Soundflower (2ch) from Internal speakers.
It doesn't take too much to change it, but it is pretty annoying and I'm assuming there's some obscure setting that can fix this.
Anyone able to help?

This fixed it on my Mac Pro. It might work on a MacBook Pro.
Delete these three files:
/Library/Preferences/com.apple.soundpref.plist
/Library/Preferences/Audio/com.apple.audio.DeviceSettings.plist
/Library/Preferences/Audio/com.apple.audio.SystemSettings.plist
Reselect whatever sound device you want as your default in the Sound Preference Pane.
Restart the computer.

I too am experiencing this issue after upgrading to Mavericks. Headphone audio balance seems to always stick to the far right. When moved to the center, it still only outputs sound to the right side. I have to constantly adjust the setting a little to the left of center for both sides to output sound equally.

IPad2: After upgrad to iOS 8, video output lost left and right side

I have a cable for my iPad2, once plugged in the bottom slot, it outputs video to TV Component port and audio to my amplifier. It's been working for years. After iOS 8 upgrade, I notice the video output lost left and right side. It's like
[before iOS 8] Apple iPad is a wonderful product for me.
[after upgrade] iPad is a wonderful product
The "Apple" on the left, and "for me." on the right of screen is gone in output.

Change your Aspect Ratio on your TV to 16:9

After upgrading to iOS 5.1, the sound output works abnormally.

After upgrading to iOS 5.1, the sound output (the 3.5mm output) works correctly only when Apple provided headphones or certain headphones are plugged in. Others cause the iPod to produce sort of phased out sound with lots of digital, low-quality sounding artifacts. Other headphones have no problems since they work fine when plugged into my MacBook.
Anyone having similar problems? Solutions?

Could be due to a defective headhone jack in the iPod that just coinsided with the iOS update.
However, to rule out a software cause, try the following.
- Reset the iPod. Nothing will be lost.
Reset iPod touch: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Restore from backup
- Restore to factory defaults/new iPod.

Sound problems after iOS 4.2 upgrade

Experiencing very poor sound quality after iOS 4.2 upgrade. Bad eq, left channel dropping out, sounds like heavy reverb. Exists with iPod and pandora apps. Tried adjusting eq in settings. Any one else having problems?

Yep I just upgraded to new OS 4.2 on iPhone 4 and I get this static buzz sound when talking to people it's really annoying and sound quality is terrible. What happened? I went back to the shop and they said it's the upgrade and that there is an issue with it. They also said there is no point leaving the phone with them as they can't fix it that it's upto apple to release a patch for the problem. Can we get a fix for this soon before I damage my ears?

I lost sound shortly after iOS 6 was down loaded. Sound works headphones.

I lost sound shortly after iOS 6 was down loaded. Sound works with headphones. When no headphones are plugged in and I try to use the volume control on side sound effects comes up but no sound is made. I get sound over main speaker when i adjust alert volume. I restarted and downloaded iOS 6 update with no results.

Try this:
1. Settings>General>Use Side-Switch To>Lock Rotation.
2. Double-click the Home button and swipe Task Bar to the right.
3. Make sure the button on the far left of Task Bar is not muted

IPad 3 sound issues after iOS 8 upgrade

iOS sounds and some apps have very little or no volume after iOS 8 upgrade.

Hello mhael,
Thank you for participating in the Apple Support Communities.
If you experience popping sounds and distortion from your iPad Air speakers after updating iOS, start with the troubleshooting steps in this link:
If you hear no sound or distorted sound from your iPhone, iPad, or iPod touch speaker - Apple Support
All the best,

After IOS 8 the sound in my apps is not working as it should.

After about 2 secunds the sound dissapear. The app i s made in 32 bit with phonegab. It is only in the new IOS 8 the problem is.

The problem is in the apps I developed and it is on all devices I have with IOS 8. I still think it must have something to do with the system IOS 8 and not the device....maybe others app developers have the same problem after IOS 8.

Problems with sound from external speakers after iOS 5.0.1 update

Have others experienced problems with external speakers on the Iphone 4 after iOS 5.0.1 update? My phone no longer rings, sounds when i receive a text message, sounds alarm, etc. Vibrate works fine and when i plug in headphones I can hear music through the headphones. Any fixes for this?

Hi Guys,
I have post eariler on another forum and I have the same problem, I have tried all the things listed here and nothing was perminant in fixing this painful iphone hating problem.... and failed. You probably have the problem when you use youtube or your music external speaker that there is no volume bar and no sound.   I have had the same problem But I need to happily say that I now have the fix!!!! This worked for me and I fixed it by myself so you don't need to go to apple or service centre or anything.
Ok I like so many of you here truly believed this was as IO5 issue as it only dropped the sound on the speakers once that IO5 update came along. I tried a bunch of reset, reboots, home clicks, lock and unlocks, to fix this and all failed. some worked for an hour but then failed. hours of my life that I will never get back.   but since I have learnt this is not a IO5 problem but a hardware issue! ... and in paticualar is has to do with your bottom connection. Your phone is thinking it is docked all the time.
To fix the no sound problem what you need is...
1. a torch
2. a tooth brush
3. methalated spirits
4. a butter knife
Step 1.
get your torch and shine it down the bottom connection plate to see what kind of dust, sand, hair or anything you have stuck in there.   all that need to be removed! everything! it might look clean but still thats ok go to step 2.
step 2.
Turn on your music app and put the speakers on! If your phone is like mine it should not work. you most probably don't even have the volume display to turn it on but its ok, just do it! and it should still play with no sound.   its important you try and run the speakers as this will show you that it is a hardware problem.
step 3.
Dip your tooth brush into some methated sprits.   then at your sink tap the exess metho out of your brush as you just want the brushes to be slightly damp, not soaking wet and then scrub the bottom connetiors on your iphone. work the brush back and forward in a way that scoops the dirt out of the phone, not just pushing it side to side.
(As you bushing you should notice the volume bar come back on or off as you scub.   This happened to me and that is how I realised I was on the right track to fixing this problem as I was doing something external that was actually controling when the volume display came on or off.   but once I cleaned it this still didn't fix the problem...)
Step 4.
Use the back side of a butter knife (not the sharp side) to gently slide over the connectors on the iphone. Do this gently as you are only pushing down on the tiny metal contect bars and you should notice the volume display come on again. slide it back and forward. Now the area of interest is about 2/3 along the connection plate to the right.   This is the area that has the infomation sent when your iphone thinks its docked.
This has worked for me and I have not had a problem since I did this 2 weeks ago.   I have since learnt that the new IOS 5 has activated a different part of the bottom conectors. if you have been using dodgy connectors or unapproved apple cables (as I was) any damage or hair and dirt on the terminal this is effecting it. Try it.   just remember if you can do something external to your phone then there lies the problem.
Hope this works for your phone as it did for mine.
Cheers

Digital sound output only after using Headphones

i used my MacbookPro 17 2.66
with headphones to listen to music and after i removed headphones there is a red light in the headphone port and only digital sound output option in system preferences control panel
If i reinsert headphones, headphone output reappears
Where are my internal speaker option gone
i have a time machine backup
Can i just replace sound preferences
Thanks

Generally that means your headphones' plug is not exactly to dimensional stands and has jammed the internal connector in the jack to the "mute" position. The plug's tip-to-shoulder distance seems to be the variable.
I've found with my MBP that, with non-standard plugs, inserting them only until they function--not until the "stop shoulder" hits the MBP case--prevents this. I have an old and cheap set of external speakers whose plug works perfectly. A patch cable I use to connect to my desktop sound system has a non-standard plug, and I have to leave the plug slightly out of the jack to prevent the problem you see. Again, insert until you hear proper sound to the device, not by feel. I've no problems with the plugs falling out using this technique.
The "official" fix is a new logic board but most people are able to free the internal contact by inserting a plus into the jack and gently wiggling it in the horizontal plane. One person recently said he freed his with a wooden toothpick.
If you use anything other than a standard plug to manipulate the jack, be certain it's non-conductive. BTW, if you use the "Search Discussion" option in the upper right of this page and search for "red light" (use the quotes) you will see a number of threads here on the subject.

No sound after IOS 4.1 update

I really hope someone can suggest a solution. I updated my iPhone 3G to IOS 4.1 earlier today and since the I have lost all sound - no keyboard clicks, music or alerts. Has anyone else experienced this and could you offer a suggestion?
Many thanks

No sound for my iPhone 3G after iOS 4.1 update! Restored back to 3.1.2. Still no sound! (befor the 4.1 update, everything was fine).
Then I reset all settings, sound came back. But then iPhone started to freeze randomly, with increasing frequency to the point I needed to restore again. This time back to iOS 4.1. And guess what - no sound! Resetted all settings. Still no sound.
Key points:
* sound loss is software issue that came with iOS 4. (i was able to get sound back after settings reset but only on iOS 3.1)
* iOS 4.1 makes iPhone unstable both on 4.1 and earlier versions.
* restore has no effect (I never restored from backup, started as a fresh phone)
* iOS 4.1 destroys your iPhone 3G

After the new update of the latest iOS, I noticed a yellowish color on the sides of my iPhone 5 screen (Top,Down,Left,Right). Does anyone know how to fix this? Thank You.

It is highly unlikely that any iOS update could cause this.
Try a restore as new, if the problem persists, take the device to Apple for evaluation.

After iOS 8, no sound when playing video taken from the back camera..

I have an iPhone 5, everything was fine before the update, but after ios 8, when i record a video from the back camera only, it plays no sound. The front camera works fine, sound and picture are perfect during playback, back camera just picture, no sound.. Anyone else have a similar issue?
