I have Ubuntu 12.04 installed as SA system in my Dell6410. The Audio card is Intel IbexPeak HDMI The problem is that I cant get audio the audio card to play 5.1 sound through the HDMi/Display port. I only get Analog audio

The Laptop is connected through Display Port/HDMI cable to the TV. The TV is connected with an optic cable to the receiver (5.1)

aplay -l:

 List of PLAYBACK Hardware Devices <br>
card 0: Intel [HDA Intel], device 0: STAC92xx Analog [STAC92xx Analog]<br>
  Subdevices: 1/1<br>
  Subdevice #0: subdevice #0<br>
card 0: Intel [HDA Intel], device 3: HDMI 0 [HDMI 0]<br>
  Subdevices: 0/1<br>
  Subdevice #0: subdevice #0<br>
card 0: Intel [HDA Intel], device 7: HDMI 1 [HDMI 1]<br>
  Subdevices: 1/1<br>
  Subdevice #0: subdevice #0<br>

My alsamixer version is 1.0.25

Within Sound there is no Digital 5.1 Mode option When trying to test only Front Left and Front Right speakers are working

I tried everything that is written somewhere in internet and nothing. Finally I have a fresh and clean Ubuntu 12.04, but the problem persists.
