No HDMI sound on GT 120 with 185.18.08 and 180.44

Hi i can't get HDMI audio on my nvidia GT 120 to work.
I tried almost everythig i could, but without any success.

Anybody can help me with that issue or do the needed drivers simply not exist ?

Regards
Heiko Jakob

HW info:
Asus Aspire X1700
NVidia MCP73 chipset
GeForce GT 120

SW Info:
ubuntu 9.04 ($ uname -a
Linux quark 2.6.28-11-generic #42-Ubuntu SMP Fri Apr 17 01:58:03 UTC 2009 x86_64 GNU/Linux)
alsa:
1.0.18 (ubuntu package) and 1.0.19 (Realtek linux_drivers-5.11) --> both don't show any HDMI audio device. At least 1.0.19 shows me the digital output of the ALC888.
nvidia drivers:
180.44 (ubuntu package) and 185.18.08 ( NVIDIA-Linux-x86_64-185.18.08-pkg2.run ) --> both don't give me a HDMI audio device

My latest configuration is nvidia driver 185.18.08 and realtek alsa 1.0.19.

Oh.
I almost forgot: It works fine on Windows so it must be a software problem.

Update

now i've upgraded to a vanilla 2.6.29.3 kernel and alsa 1.0.20 --> Still does'nt work.
But now i can load a module called 'snd-hda-codec-nvhdmi' which changes absolutely nothing for me :-(
All new sw install --> Still does'nt work.

Problem SOLVED !!!

The Acer Aspire X1700 simply loops the ALC888 SPDIF to the HDMI Port.
Using the SPDIF as output device results in working HDMI audio.
It finally works :-)
