c# - Playing 30 sound effects at the same time repeatedly -

i'm trying play 30 piano notes @ same time in xna application on windows phone 7. have imported , loaded wave files below

    protected override void loadcontent()     {         spritebatch = new spritebatch(graphicsdevice);          sound3 = content.load<soundeffect>("1");         sound5 = content.load<soundeffect>("3");         sound6 = content.load<soundeffect>("4");         sound7 = content.load<soundeffect>("5");         sound8 = content.load<soundeffect>("6");      } 

every sound effect file less second, i'm trying play of them @ same time. play them using loop runs every second.(so @ every loop 30 sounds played goes on , plays same 30 sounds each second) works fine few seconds stops playing sound (the loop still working) again starts working once or twice , again stops working . makes bad noises if audio system cant support many sounds play @ time.

i'm not sure how can solve problem , if buffer problem or threads.

nico schertler right! i've faced same problem , fixed managing instances. when play soundeffect instance! default have hope xna/monogame care it, doesn't. when have many live instances (even stopped, breaks, noise, silence.

i hold rectangular array sound effects 4 instance each, , if have instances of sound want play instead of creating stop oldest (by timestamp), play , remember current timestamp.

see following code:

private const int max_inst_of_one_sound = 4; private soundeffectinstance[][] sndinstarray = null; private float[][] sndinsttimes = null;  public init() {     sndarray = new soundeffect[soundsschema.sounds.length];     sndinstarray = new soundeffectinstance[soundsschema.sounds.length][];     sndinsttimes = new float[soundsschema.sounds.length][];      (int = 0; < soundsschema.sounds.length; i++)     {         try         {             sndarray[i] = content.load<soundeffect>(soundsschema.sounds[i]);//soundsschema string list holder class         }         catch (system.exception)         {         }          sndinstarray[i] = new soundeffectinstance[max_inst_of_one_sound];         sndinsttimes[i] = new float[max_inst_of_one_sound];     }  }  private soundeffectinstance getvalidinstance(int sound) {     if (sound < 0 || sound > sndinstarray.length)         return null;      soundeffectinstance inst = null;     (int = 0; < max_inst_of_one_sound; i++)     {         if (sndinstarray[sound][i] == null || (sndinstarray[sound][i] != null && sndinstarray[sound][i].isdisposed))         {             sndinstarray[sound][i] = sndarray[sound].createinstance();             sndinsttimes[sound][i] = myengine.curtime;             inst = sndinstarray[sound][i];             break;         }     }      if (inst == null)     {         float min_time = float.maxvalue;         int ind = -1;         (int = 0; < max_inst_of_one_sound; i++)         {             if (sndinstarray[sound][i] != null && sndinsttimes[sound][i] < min_time)             {                 min_time = sndinsttimes[sound][i];                 ind = i;             }         }         if (ind == -1)             ind = 0;          if (sndinstarray[sound][ind].isdisposed)             sndinstarray[sound][ind] = sndarray[sound].createinstance();         else         {             try             {                 sndinstarray[sound][ind].stop();             }             catch             {}         }         sndinsttimes[sound][ind] = myengine.curtime;         inst = sndinstarray[sound][ind];     }      return inst; }    public virtual void playsound(int sound, float volume, float panoram, bool loop) {     if (sound < 0 || sound > sndarray.length)         return null;      if (!mmuted && mvolume > 0)     {         soundeffectinstance sndinst = getvalidinstance(sound);         if (sndinst == null)             return null;          try         {             sndinst.islooped = loop;             sndinst.pan = panoram;             sndinst.volume = mvolume * vol;             sndinst.play();         }         catch          {         }     } }
