Right, and what about volumes from the command line? 

On a machine I admin with a Delta 1010 the solution was a bass
management box (basically a big volume knob with some signal flow
control) on the end of the chain.  It is necessary final buffer to the
speakers, especially since the master volume controls don't want to
appear in the envy24control mixer for the 1010, but's that's a separate
problem.  Obviously, a good clean analog mixer will also do the job
(and its _much_ cheaper).

Ever heard 4 nearfield monitors pump out 24 bit "jetengine.quad_1.wav"
at maxamp (+4db) :((

Out of curiousity, is there actually a levels mixer for the Hammerfall
in Windows?  If I remember right, all you get for the Hammerfall is a
control panel for clock, buffers, etc.  Aren't you controlling volume
in Gigastudio or Nuendo or whatever anyway?

Do you have two machines/OS's here (Linux/Hammerfall lite,
Windows/HDSP)?  Then why not swap cards and let Windows/HDSP and
TotalMix control the levels for both systems from Windows (where it
does work...though I am VERY excited to test the recent "hdspmixer"
release for Linux!!)?

- Linux/9636 box: ADATs (plus S/PDIF?) into the HDSP 9652/Windows box
- HDSP into monitors/amp, ext. hardware, etc
- TotalMix controls routing in and out of both boxen and to and from
external gear, etc.

I did this for a while with a Mulitface.  I even ran the Windows box
_headless_ and just used tightVCN to control TotalMix "remotely"...plus
the few apps I still used.  It didn't matter since the two machines
were talking to one another in audio data via the HDSP/Hammerfall.

This is exactly the kind of situation where an "all-digital" card is
great.  You can get audio data in and out of the machine without signal

Just a thought.

I guess I'm a glutton for punishment, I'm still thinking about a
multiface for my home system (pending cash).  My hesitance is this: 
the memory of the extreme inner joy I felt the day my Hammerfall card
sold for good on eBay ;->
