c# - XNA small noise when sound starts or stops playing -


i made small application plays .wav files when press keys, trying play music on keyboard, there noise speakers when release key, , believe when press it. .wav file sinusoidal wave, don't think it's source of problem, clues causes sound , workarounds? noise similar momentary static gen when plug in headphones or similar.

in order solve problem, have capture 2 keyboardstates. 

keyboardstate oldstate; keyboardstate currentstate;  public void load() {     oldstate = keyboard.getstate(); }  public void update(gametime gametime) {     currentstate = keyboard.getstate();     //example below      if (oldstate.iskeyup(keys.space)     && currentstate.iskeydown(keys.space))     {        //play sound     }     oldstate = currentstate; }

what make sure key being pressed's old state , new 1 down. stop sound playing on , on again. @ end of update loop, set currentstate oldstate , start logic on again.
