There is this software issue with iOS 6 which causes the “no sound” syndrome in iPhones and iPads. Some iPod Touch users too have been affected by this issue where the iOS device would stop playing any sound (music mostly) and the volume controls are broken.
This issue has been around for a long time now and for the few users who are still on iOS 6 (due to various reasons), it can be quite bad, not being able to hear music or sound in videos. However, the strange thing is that when you get into settings and turn the volume up or down in the notification settings, you'll hear the test sound. But you won't hear music from iTunes, or see the volume bar in multi-task switching bar or in the heads-up display when you press the volume buttons.
So how do you fix iOS 6 sound problems? Here are some solutions.
1. Update to iOS 6.0.1
Apparently, Apple figured out that this was a software issue and so, in their update (iOS 6.0.1), they fixed it. Users on iOS 6.0.1 should not face the trouble. If there's no particular reason you are still on iOS 6, it's time you upgraded and fixed the sound issue.
iOS 6.0.1 is good and despite the Wi-Fi issue still lingering at times, there's no big issue that would put you off. If you are facing these sound problems, try upgrading to iOS 6.0.1 Also, iOS 6.1 is just around the corner so if you can bear just a bit, you can wait and upgrade to the latest but I would recommend going to iOS 6.0.1.
2. Check Dock Status / Bluetooth Audio / Connections
Docks can be a problem. Disconnecting from charging docks, speaker docks abruptly can cause the music to be shut off and the sound going berserk. If you've been using a dock, or connecting your iPhone to the car audio via Bluetooth, make sure all these settings are correctly configured and then disconnected. A simple thing you can try is reconnect them and check if the sound works fine. After this, disconnect properly, restart your iPhone/iPad/iPod Touch and then see if the sound works normally.
3. Reset Settings
If nothing works, a simple reset should be helpful. You can always restore from the iCloud backup (or iTunes backup) but make sure you take a backup before you try this step. To Reset, all you do is:
- Go to Settings
- Tap on General
- Scroll down and tap on Reset
- Reset All Settings
The iPhone should reboot. If things went good, your sound should be back up.
But if nothing really works, restore is your only other option. You can restore from an older backup in iTunes or directly from the Apple servers (via iTunes) by clicking ‘Restore iPhone..' when you connect the device to your system.
Restoring via iTunes will update your firmware to iOS 6.0.1.
