OK, in the log I found one section that looked promising:

2008-06-13 23:54:19.237 AFD: Opened codec 0x5a6fe50, id(AC3) type(Audio)

Obviously there is something wrong with spdif so I'm just going to try 
each of the output settings in Utilities/Setup -> General until I hear 

Thanks, I'll let you know how it went...
