After a bit more head scratching, I remembered that the sound system wasn't a plug and pray thing, there was an install script to run. So I did that, and that didn't work either, but it did produce error messages. A bit of searching on the error message suggested that I needed to alter the config.txt file. Remove one item, and add another. Following a reboot, it now works.
