Jansej,

I have deleted my .asoundrc and asound.conf for the moment, ensured my 
setitngs are as per Allens suggestions (/dev/dsp but I will try 
ALSA:default as well),  and rebooted. SPDIF passthough is definitely NOT 
checked, nor is the mixer.

When I run speaker test it runs, but I still get NO audio. Should I run 
speaker test and play with the alsamixer?

Output from aplay and speaker-test below. I wonder what I am doing wrong 
here...... Starting to look like sound is dead on this mb.

$ aplay -L
default:CARD=ICH5
    Intel ICH5, Intel ICH5
    Default Audio Device
front:CARD=ICH5,DEV=0
    Intel ICH5, Intel ICH5
    Front speakers
surround40:CARD=ICH5,DEV=0
    Intel ICH5, Intel ICH5
    4.0 Surround output to Front and Rear speakers
surround41:CARD=ICH5,DEV=0
    Intel ICH5, Intel ICH5
    4.1 Surround output to Front, Rear and Subwoofer speakers
surround50:CARD=ICH5,DEV=0
    Intel ICH5, Intel ICH5
    5.0 Surround output to Front, Center and Rear speakers
surround51:CARD=ICH5,DEV=0
    Intel ICH5, Intel ICH5
    5.1 Surround output to Front, Center, Rear and Subwoofer speakers
null
    Discard all samples (playback) or generate zero samples (capture)
