No problem. Are you using the kernel OSS or the commercial OSS drivers?
Anyway, you could use:
# 2 channels per recorded file, 32bits, 44100
ecasound -f:s32,2,441100
-a:chain1 -i /dev/dsp0 -o foo1.wav \
-a:chain2 -i /dev/dsp1 -o foo2.wav \
-a:chain3 -i /dev/dsp2 -o foo3.wav
The exact syntax (ie. can you use /dev/dspX syntax to access individual
stereo pairs), depends on the used drivers.
