This fails because you've used direct hw-access ('alsahw') to the
soundcard hardware. No implicit software adaptation is done in this case
by alsa-lib, and the application must use audio parameters supported by
the hardware. In this case, Delta66 doesn't support stereo recording, you
always have to record all the 12 channels of the chip. Normally ALSA hides
this complexity from the end-users, but if you want to be sure no
conversions are done in software, you can request for direct hw-access
(but then you have to set the parameters correctly).

Solution 1: Use the ALSA plugin layer

ecasound -i alsa,plughw:1 -o foobar.wav

Solution 2: Record all the 12chs

ecasound -f:32,12,44100 -i alsahw,1,0 -f:16,2,44100 -o foobar.wav
