Oops, I'm really sorry: I added the wrong file to the archive. If it's
any use, the file I actually intended to upload (still 32-bit floats
recorded through Jack, I'm afraid) is here:

Here's one seconds worth of 12 channels recorded with arecord, with 
440Hz of (approximately) sine wave in channels 1, 2, 3 & 4, and silence 
in the rest:

(There are 12 capture channels on the UA-1000: 1-8 are analogue inputs, 
9-10 are the SP-DIF, and 11-12 are a mix of the output signals.)

I hope this is more helpful than my previous try.

Cheers,
Colin.
