iPhone not syncing mulitmedia after iOS 8 update

i got the same problem..

I am having the same issue. I enabled cloud drive and it looks like the music is in the cloud and will only be downloaded upon playing the particular song or album. It will not synch my entire library back to my phone.

I Had the same problem too but what I did was I went to devices on itunes. Then on my iPhone > summary > options > (click) Manually manage music and videos. Then synched. I had to sync twice until it began to download it all.

I also had this issue - well, whilst updating to ios8 the setting for itunes match was turned from off to on - not sure why apple think it's fine to do this. Never had this happen before!?

this resulted in all my music on iPad and iPhone being deleted. Then whilst trying to copy the music back after the upgrade was complete, the synch to my MacBook crashed and I was left with huge chunk of 'other' data that was in effect the music data but it wasn't being recognised by the devices.

Ended up having to do a restore - which lost lots of in app data - and still need to synch the music on to my iPhone properly. Currently it shows the music as selected and installed within itunes but there is nothing on the actual device. Soooo annoyed that apple have decided to toggle on iTunes match during the ios8 update - has taken hours of my life up for no reason!?

That did the trick! Thank you! I had to synch three times before it took, but it did work.

The option os gone... Anyone had that issue as well??

Nevermind. I got it!! I had to switch the "itunes match" off on my phone. After that, the "music" showed up on the manually option. Thanks.

I've found the quickest way to sort the problem is to uptick the music (or whatever media) from iTunes and sync your phone without it. Then tick it again and sync. Worked for me

I can´t sync my iPhone 4s anymore after updating to iTunes 11.4 (OSX 10.6.8) and IOS8. My iPhone appaers and is shown with the correct contents (Storage-Bar in Itunes. But actually the phone is empty. No pictures, videos & music.

The sync button is grayed out. As soon as i make changes to the sync-setup the sync starts but stops immediatly after a second with no error.

Can anyone help me?

I'm having the same issue. It appeared after i tried to sync a song I had added on my library. It didn't sync the song and deleted all of the songs instead. I unchecked "sync the music" and it seems to have deleted all of the songs from my iPod. Physically speaking, i couldn't see them anymore in my music app. So i tried to sync everything back and it seemed to be working. When i checked the sync this morning, half of the songs lack of artwork and Itunes tells me there is no music on it.
I've had the same issue in the past and a restore was the only solution I had. I'm just trying to avoid it since it's extremely long and it makes you lose app data. Right now, I have to delete all of the music again. I guess I really have to restore.

Same issue here. iTunes 11.4 on iMac, just upgraded to iOS8 and had to do it through iTunes on the computer because not enough room. Had to keep syncing my iPhone 5S to get the apps to load, then music disappeared. I've freed up plenty of space but it still won't load. I don't have iTunes match so not sure what to uncheck (it has an option to subscribe in settings).

I had the same issue with music files missing after iOS8 update. Selecting 'manually manage music and videos' and then syncing put all the music back.

same problem here also. will try to fix it later .

thanks all
