attack sound for custom projectile?

not sure if this would fall into modelling forum or not. I currently made a new attack projectile from scratch. However whenever i use it in game i cant here any noise from the attacks now. Anyone know how to correct this?

Did you make it in 3ds max or something else?
If in 3ds max...

• Add a birth animation in addition to your stand.
• Create a helper and name it SNDXMARL, changing MARL to the id of the sound you want, as found in Ui\SoundInfo\AnimLookups.slk .
• Add a note track for that helper and notes wherever you want the sound to play (at the beginning of the birth animation.)

If in the MDL:

• Add a new sequence named Birth. Make sure it's NonLooping.
• Add a new pivot point at 0,0,0. (Position doesn't really matter)
• Add a section like this at the end:
  
  Code:

  EventObject "SNDXMARL" {
  	ObjectId 3,
  	EventTrack 1 {
  		2667,
  	}
  }

• Change 3 to the ObjectId after the last one you already had.
• Change 2667 to the beginning from of the birth.
• Change MARL to the id of the sound you want, as found in Ui\SoundInfo\AnimLookups.slk.

Thanks mon... is there any particular reason it needs to be in birth animation? cause i added it to my stand animation instead seemed to work. Also do you absolutely have to add another pivot point or can u use pre-existing ones? Lastly is there any way to make your own MARL sound?

Adding a new pivot point is best. It's not hard, either.

Birth just because then it will play when the thing is shot. I guess stand would work too, though, so either one.
As for making your own MARL, I'd recommend picking a sound you're not using from that table, referencing it, and importing your sound over it in your map.
