Massive Airplay-Problems with Macbook Pro 13 Late 2013

Hi,

since upgrading to Yosimite and iOS 8.1 I got many, many massive Problems with my Apple-Devices.

The most of them are already solved (Since 6 Month I'm almost every day in contact with Apple Support........)

The Main-Problem now is Airplay.

At home it works "ok", sometimes a bit laggy.

But at work, it shows a Airplay-Receiver, that is at my home....

And it wont disappear, except I kill "coreaudiod" or restart the Macbook.

Every day it came back... (When I was at home...)

And: Peer-To-Peer Airplay wont work with my Apple TV 3 on work.

On iPhone 5s, 6Plus and iPad Air it works very good!

What can I do?

(Sorry, for the bad english. I'm german)

Problem description:

Airplay

- I’m at work, but the „Sound“-Icon shows a Airplay-Receiver, that is at home.

It is not possible to delete it (Execept to kill „coreaudiod“)

- At Work, I have a Apple TV 3, that wont work via Peer-To-Peer-Airplay.

I got a Macbook Pro Late 2013, that should support this feature.

But only in 5% of all cases a connection is possible.

On iPhone 5s, iPhone 6Plus and iPad Air it works fine!
