There are two possibilities I can think of. One is that you're using pulseaudio and not checking its volume level (to confirm this, start alsamixer and press F6 to select a different 'card'). Alternatively, the windows driver might know about some control on your sound card that ALSA doesn't. Check the ALSA webpage for information about your sound card (you didn't say what it was) and see if anyone's reported bugs.
