Malith,
You need to create more than just one bullet object as your projectile. Instead, create enough bullets that you will not cycle through them all before the last bullet shot runs out of 'life'. Let's say that each bullet's life will last to 300 units out, and their speed will be 5 units each frame(game loop). Let's also say that you wish to shoot a bullet every 5 frames, as long as the 'trigger' is held down. Let's do some math.
Simply, divide the bullets' lifes by the distance they will travel each frame. 300 / 5 = 60. So, we need 60 bullets to make this loop fluent.
Now, there is a need for an array to control all the properties of each bullets. What do we need to record? In the 2D program I need to record the bullets' x and y coordinates. In 3D, you may need to record their z coordinates. Also, their bulletlife, in which this value will also be used to make the bullet move if it is above 0 bulletlife. Lastly, bulletangle.
There is no way to correct the sound problem the way you are writing the code, because you are only using one bullet, and AS SOON as it dies, it is reset and the sound is played again.
The code snippet below is a small program made in order to show this loop working. It is all in 2D, however, we're not focusing on the graphics, but the loop. The code is heavily commented to guide you through it processes. Watch for the "THIS IS WHERE YOU PLAY THE SOUND" comment. Enjoy!

REM << count2 is incremented after each delay and used as which dimension in the array to be edited(lamen:which bullet is being fired)
inc count2
REM << if count2 goes above the amount of bullets(in this case 60, then reset it to 1)to continue fluid loop of bullets moving
if count2 > 60 then count2 = 1
REM << now, let's prepare the bullet, # of count2, which is going to be fired, by setting its properties
bullet(count2,1) = playerx# + (cos(playerangle) * 20)
bullet(count2,2) = playery# + (sin(playerangle) * 20)
