> Thanks to Rocco and Eric for the help!  Before Rocco's email, I had worked out the -f:16,2,48000 for the output to get stereo going to -o alsa,default.  However, only the first two input channels were audible.  Looking at the man page, I found that -erm:all,1 -erm:all,2 mixed all the chains to the stereo output.  However, the volumes were weird - the volumes of chains 9 and 10 were much louder than the others.  I saw somewhere on the web that ecasound scales volumes by 1/N when mixing, but it seems that the first two chains are "passing through" at their original volume.  Any pointers on getting the volumes set correctly?

I've never owned a multichannel sound card (other than the two channels 
of my sterio card) so I'm not sure how all that works. But (I think) 
this is the link for the ecasound mailing list...

There's an ecasound list archive also that you can search for key words 
and may find answers to your questions.

Ecasound has a bit of a learning curve and a few quirks that aren't very 
obvious. But it's well worth sticking with it. I keep discovering more 
and more uses and features as time goes by. And when you figure out the 
quirks, it works beautifully.
