Hi Clemens,
   Thanks for responding. I *think* this was my problem. It seemed
that alsaconf didn't find the card until I actually built the driver.
That was a bit of a Catch-22 since I didn't know what driver to build,
etc. Anyway, after building the driver based on Stephen's input
alsaconf found the card, it's installed and mostly working. The only
app I'm having trouble with so far is MythTV which says it is
controlling PCM but doesn't actually control PCM on this card. IT
works fine on all my non-HDA systems. That may be a MythTV problem, or
maybe it's a driver problem we could look at since it will take months
to get the MythTV people to pay any attention to a problem like this!
;-)

   Let me know what other information would be of interest.

Cheers,
Mark
