Patrick,
   This was interesting. With this file in place the card was locked
into 48KHz and the controls in hdspconfig wouldn't change it. I wonder
why? Did this allow Alsa to lock up the card so that even hdspconf
couldn't get to it? If so that's going a bit too far I think.

   As soon as I removed the file hdspconf worked again...

   Thansk for the ideas. I think they may be part of the solution eventually.
