I have never run it in Windows. On LM 16 I use the pulseaudio mixer which when switched to headphone output does not provide the low impedance option. On openSUSE 12.3 using the kmix mixer from KDE3 I get 3 impedance options to choose from. Not sure how it helps you but the option you want is certainly available here on openSUSE. Something for ALSA devs to answer ?
