Try ecasound for starters. It is great commandline software for 
multichannel recording and I have tested it with 1010LT.

10 channel recording goes like:

ecasound -f 32,10,96000 -i alsa -o 10ch.wav

-f is the format; 32 bit, 10 channels, 96000Hz

You might need to specify the alsa device to use, if your motherboard 
soundcrap^H^H^Hcard uses alsa too

I'm not sure if this has something to do with Audacity not being natively 
alsa-compatible. It uses alsa through Portaudio, but I don't know whether 
that's same as natively using alsa. You could try getting oss-drivers for 
Delta1010LT (they are nowadays free of charge from www.opensound.com) but 
I really can't say if that does the trick.

Better ways may exist, like ecasound and ardour

Please ask more if this was not s--l--o--w enough. (And I know it was not, 
so I'm expecting questions)
