I have a soundcard (Audigy 2ZS), which is very old and very poorly supported in modern Windows OSes, but this sound card has very important feature - when I use microphone, I can hear my own voice through the headphones with absolutely NO delay (i.e. I can monitor my voice in realtime) - as opposed to standard windows feature of "playback of recording device", which creates a delay of ~1 second, which is unacceptable.
Is there a way to eliminate that delay in standard windows functionality?
