This does sound as though it might be the cause of my problem. The card *was* previously in a Mac - I asked on this list earlier whether it would be compatible, and someone said it was. I probably wasn't very clear. Is that the chip that sits in a slot on the card? Is it an EPROM that I can get hold of and replace myself? I seem to remember seeing chips for RME cards labelled with different revisions on eBay... >>I've plugged the card in, and run alsaconf.

This is a Hammerfall Light 9636. Are we wrong? At the moment, I'm either setting the switch on the ADA8000 to 'Master', or to 'Slave: ADAT in'. On either setting, the 'Sync locked' light on the ADA8000 turns on. Thanks Michael
