Ok so I have looked through a few threads and followed a heap of how to's and managed to get the HDMI Audio showing up in Gnome sound preferences.
First my setup

Asus p6t motherboard
Asus EN210 video card
Intel i7 930

lspci |grep -i audio
00:1b.0 Audio device: Intel Corporation 82801JI (ICH10 Family) HD Audio Controller
02:00.1 Audio device: nVidia Corporation High Definition Audio Controller (rev a1)

cat /proc/asound/devices
0: [ 0] : control
1: : sequencer
4: [ 0- 0]: hardware dependent
16: [ 0- 0]: digital audio playback
17: [ 0- 1]: digital audio playback
24: [ 0- 0]: digital audio capture
26: [ 0- 2]: digital audio capture
32: [ 1] : control
33: : timer
36: [ 1- 0]: hardware dependent
37: [ 1- 1]: hardware dependent
38: [ 1- 2]: hardware dependent
39: [ 1- 3]: hardware dependent
51: [ 1- 3]: digital audio playback
55: [ 1- 7]: digital audio playback
56: [ 1- 8]: digital audio playback
57: [ 1- 9]: digital audio playback

Like post 13 here I have managed to get pink noise using the below
speaker-test -Dhw:1,7 -c2
speaker-test -Dhw:1,3 -c2

I have upgraded Alsa to 1.0.23 using backports, and have played with asound.conf but I have found if the file exists I have nothing in /proc/asound/card1

Oh yeah contents of /proc/asound/card1
codec#0 codec#1 codec#2 codec#3 eld#0.0 eld#1.0 eld#2.0 eld#3.0 id oss_mixer pcm3p pcm7p pcm8p pcm9p

cat'ing any of those eld files gives the same result:

monitor_present 0
eld_valid 0
monitor_name
connection_type HDMI
eld_version [0x0] reserved
edid_version [0x0] no CEA EDID Timing Extension block present
manufacture_id 0x0
product_id 0x0
port_id 0x0
support_hdcp 0
support_ai 0
audio_sync_delay 0
speakers [0x0]
sad_count 0

Anyone got any tips or advice, I really want to get HDMI with HDMI audio working on this new box as it is my new media center and virtual server.

hmm pavucontrol and alsamixer failed with an ~/.asoundrc file that was mentioned in another thread.
I think in my case the plot is a bit thicker, without that .asoundrc file I seem to get the audio meter on pavucontrol displaying sound on the HDMI but nothing through the TV, so either it is a faulty cable or a fault with the TV. I am going to have to loan the cable to someone and see.
