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

My lap has also a built-in soundcard ESS maestro 3 (number 1870 i think), but in my case i/o is limited to just 1 mono input and stereo out (the output quality isnt too bad).

hey there, i have the same card in my laptop, and the same mono-input limitation... but when i bought it, they told me that the input was stereo... i have a feeling that this is a flaw in the linux driver, but i've never been able to test this under windows because i have a linux-only install. can you remember if the input is stereo/mono under windows?

tnx pix.
