If it's any use, the file I actually intended to upload (still 32-bit floats recorded through Jack, I'm afraid) is here: http://www.starlingaudio.co.uk/misc/received.wav.tar.bz2 > Floating-point samples (as used by e.g. Jack) don't show what bits the > device sent; please use arecord, like this: > > arecord -D hw:UA1000 -f S32 -r 44100 -c 10 something.wav 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: http://www.starlingaudio.co.uk/misc/arecord-test.wav.tar.bz2 (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.
