'K.  Thanks. . . .

If it's not a big deal, then I'm not going to worry about it. . . .

I did (leaving qjackctl at its defaults), without any success -- and not 
just not seeing anything on the VU's; I couldn't even get a demo to play 
in Hydrogen. :-(

That I hadn't thought of.

After reinstalling FC 3, &c, &c, it seems that all is working.

What would be considered reasonable output levels in envy24control (I'm 
guessing I'll have to do gain adjustment on the (mic) inputs; at any 
rate, I had to in Windows)?

Thanks to everyone for all your help.  I wish I knew what went wrong the 
first time around . . . but right now I'm just relieved to be able to 
get sound on the Linux side.

So now I guess I get to spend time trying to figure out how this stuff 
works. . . . :-)
