I have tried a config with an analogue set up and got no sound either.

I guess I could be doing something really stupid in the config as I'm not that familiar.

Is it likely that both the analogue and digital out boards have failed or is a problem with the EF, CD or FICL cards? What do they do?

What does the LM317T on the motherboard supply?
