But I was able to get skype working with the use of skype_dsp_hijacker.

I'd already made an icon to run it, and changing the command from 
'usr/local/bin/skype' (note quotes) to skype_dsp_hijacker --2nd
without the quotes as they seemed to screw up the argument passing, that 
seems to be working now.  It seems that the hijacker actually functions 
as the skype launcher, something not noted in the README in large 
enough print to get my attention.

So the remaining problem is the fouled nest kmix seems to be living in 
when the Audigy 2 Value [SB0400] device is selected.  All controls are 
placed on the output tab, making its window about a foot wide.  Is 
there any cure for that other than upgrading kde to 3.5?

Cheers, Gene

stupid bounce rules.  I do use spamassassin too. :-)
