Sorry for the preceding message that was automaticly sent before i finished
all tests, THIS IS WHAT IS TRUE and not what i said in my preceding message
answering you.

In Win (ME, maestroESS 3 driver) the input is NOT stereo. Sorry for my first
wrong appreciations. Plugging a stereo source in the input both in windows
and linux is treated as a mono source leaving out one of the channels. So in
pd both adc~1 and adc~2 output the same (mono) signal that matches just one
of the channels channel of the stereo signal you plug in the input, although
recording from CD works fine outputting a stereo signal. Plugging in a
stereo source in windows produces the same behaviour.

The techincal spec sheet states that A/D and D/A is 16 bit stereo though.
The soundcard input plug has a little MIC painted on it and its behaviour IS
as if it were a standard mono mic input. The input is controlled in both
mixers (win&linux) by the MIC input fader (maybe this has something to do
with the mono trouble?).  The Win mixer has a +20 dB switch to handle
both line and mic levels.

By the way the right soundcard model is Maestro ESS 3, chip 1980
