I have home sharing turned on on both of my computers and my iphone, but I don't see how to get them to share music

Hello hueycat,

Thank you for the question. It sounds like you have enabled Home Sharing on your devices, but you are not seeing the option to share music. To use Home Sharing, your devices will need to be on the same network. I also have some additional suggestions to get you setup with Home Sharing.

On the computer, I find it useful to have the Sidebar enabled so that you can see the iTunes libraries that are shared:

In iTunes 11 you have the option to turn the Sidebar and the Status Bar on or off; they are off by default. To do this in the menus, go to:

Show Sidebar - Choose View > Show Sidebar (this feature will display iTunes features on the left side of the application including Library, Store, Shared, Genius, and Playlists).

Once you have that enabled, you should see the shared iTunes library in the Sidebar:

On your iPhone, I you can view the shared content in the Music or Videos app:

iPhone

1. With iOS 5 and later, tap [Music or Videos] > More... > Shared or tap iPod > More… > Shared with earlier versions of iOS.
2. Select a shared library.

If you are using Home Sharing to transfer your iTunes Library from one computer to another, use the steps in the section titled “Home Sharing” in the following article:

Lastly, if you are not seeing your shared iTunes libraries at all, you can use the steps in the following article to troubleshoot Home Sharing:

Thank you for using Apple Support Communities.

I updated to iOS 7.1.1 and home sharing started to work again.
