Should not be required or useful (as far as I know) for the DIGI9636.
hdspconf and hdspmixer only work with the HDSP cards, not the older
Hammerfall cards.

This is a common mistake. I make it about 40% of the time people write here...

You should not need any config files. I don't use them. There is one
file which is created by the system called /etc/asound.state which
sometimes is outdated by Alsa updates. If that happens you'll get
messages when Alsa starts (probably boot time for you - what distro?)
and the messages will say things like a 'control' has incorrect
values, etc. If that happens just erase asound.state and let the
system create a new one.

Will look in and see if I can help.
