Change icons in the right corner?

[Henrik Jansson]

Hi!
How do I change the look of the icons in the right corner in Linux Mint 17.1 Cinnamon? ( clock, loudspeaker, connection, and so on)
I have tried alot of themes and icons, ant that changes most of the other icons, but these icons always looks the same in the same boring ugly way.. How do I change them?

When I had Ubuntu 10.04 and also in Linux Mint 17 mate these icons also changes when I change other icons.

When you tried changing themes, did you reboot or restart Cinnamon right away? Those may not change until you do.

No, not right away, but all other icons changes immediately. But this icons in the right corner, network and loudspeaker did not change, and after rebooting either.
