Sound check is not working properly??

I have this problem too and it drives me insane. I can listen to a few tracks and then the volume increases significantly. If I forward to the next track and go back to the track with the issue, the volume is okay.

I've...

• Having "sound check" enabled in iTunes and enabled iPhone 4s.
• Having "souch check" enabled in iTunes and disabled iPhone 4s.
• Having "souch check" disabled in iTunes and enabled iPhone 4s.
• Having "souch check" disabled in iTunes and disabled iPhone 4s.
• Used iTunes match and removed iTunes match.
• Purchased iVolume to check every track in my iTunes library.

I'm 99% sure the fault is on the iPhone 4s.

I previously enabled iTunes match (what a mistake that was), and disabled it again. Not sure if the problem existed before I enabled iTunes match.

If Apple cannot get this problem sorted out soon, I may venture to the other side!

Managed to resolve my issue. Found the solution after reinstalling iOS 5.1.1 on my iPad which was suffering from not being to delete Genius Mix playlists.

The issue is that the iTunes library stored on the iPhone is corrupt. The only way of resolving the issue is to reinstall iOS and copy all existing apps/music/content back to the device.

I've been playing my iTunes libray on my iPhone with about 100 albums and they're all playing at the same volume level. 🙂

I have the same issue

and... i did your solution, but it doesn´t work 😟

I did a Backup first, then i restored the iOS and When it is finish , i Loaded the last backup

Testing the music and the problem still appearing.

Thanks.

PS: sorry for my english.

Here it is five years later and Apple still hasn't fixed sound check. I'm on an iPhone 6s and get tracks at wildly varying volumes. The lumineers should not be louder than zep!
