No HDMI audio output - Win7

[Nocturnal21]

Hey guys!

I purchased my new notebook a month ago and I tried connecting it via HDMI to my TV. I have no trouble with the video output, but with the audio output. Normally in the audio menu (I think it's called playback devices in english,... I'm german) I would be able to select HDMI output, but it's not shown there, though all outputs to display is enabled. I deinstalled and reinstalled the Intel driver several times, but nothing changed... Display and audio drivers are up-to-date

This is my config:

Windows 7 Professional x64
Intel i7 - 4550U
Intel HD Graphics 5000

What is shown?

In the playback devices only this:

• 
  ■ Speakers
  ■ Realtek HD Audio 2nd output

... and nothing else
When I plug in the HDMI cable, nothing happens

I already did all the things as suggested on the intel site. Even the driver reinstall as I mentioned.
Nothing helped. Still no HDMI audio.
