I am using this attached code but no matter where I put the volume code line it has no effect, I need to have the ability to change the volume.
I thought I knew what I was doing but it turns out not to be case. Should be simple, right? I could sure use a little guidance.

Thanks for any help.

--Function requires the same name as the file
local soundPlaying = 0
local vol = 20 -- water volume 
local trigger = 3000 -- activate distance
local sound_entity = 125 --entity assigned to this lua file

function river_sound_init(e)
end

function river_sound_main(e)
  if GetPlayerDistance(sound_entity) < trigger then
	    LoopSound(sound_entity,0)
	    ActivateIfUsed(sound_entity)
	    if soundPlaying == 0 then
			PlaySound(sound_entity, 0)
	      	SetSoundVolume(vol)
	      	soundPlaying = 1
	    end
	   	else
		if soundPlaying == 1 then
 			StopSound(sound_entity, 0)
 			soundPlaying = 0
 		end
 	end
end

You have the sound playing twice, SetSoundVolume only controls the last instance of sound when it is called, therefore you're only reducing the volume of one instance of the sound.

Try this

+ Code Snippet

--Function requires the same name as the file
local soundPlaying = 0
local vol = 80 -- water volume 
local trigger = 3000 -- activate distance
local sound_entity = 125 --entity assigned to this lua file
 
function river_sound_init(e)
end
 
function river_sound_main(e)
  if GetPlayerDistance(sound_entity) < trigger then
        ActivateIfUsed(sound_entity)
        if soundPlaying == 0 then
            PlaySound(sound_entity, 0)
            SetSoundVolume(vol)
            soundPlaying = 1
        end
        else
        if soundPlaying == 1 then
            StopSound(sound_entity, 0)
            soundPlaying = 0
        end
    end
end

@smallg
Thanks for the advise. Sadly it still does not work. Are we sure the volume command really works at all. I have run the code you listed with several different values for the volume variable with no volume change. (What are acceptable value range limits for set volume anyway)

I am using a 30 second wav file. What I am trying to do is create a simple lua file that allows the sound of the river to play when ever the player enters certain areas along a trail that some times is adjacent to a river, thus the requirement for the river sound. With out the loop command, if the player enters the trigger area and stays longer then 30 seconds the sound stops, just as though he had left the trigger area. I need the sound to continue as long as the player is standing in that trigger area. When this happens after the 30 seconds, the player can no longer activate the sound by entering or leaving the trigger area.

My original code, with the loop command, does this with out fail but I have no control over the volume. It appears that the code, without the loop also does not allow me to control the volume. I'm confused. I need the sound to continue for the duration of the players time in the trigger zone and be able to be activated at different spots along the river.

make the sound you are using a mono wav, this will pan and fade as you move, a stereo ogg file is just that, stereo.

I dont know if this is what you are looking for. This was my first script i ever created for my father, didnt think it was so good, but it works well. And you can change the distance it's starts playing the sound.
Just add the script to an object and add a sound in the sound0 property of the object and you are good to go.

Thanks to everyone.
I have what I want now and it works fine. (see the attachment) I still have a problem with the volume though.
I will take a look at the code from roandoom and see if his volume code works for me.

Again thanks to all, you have all been very helpful.

Edit: I have the sound volume now working. The problem is that the volume range is about 85 to 100. Anything below 85 is almost silent. 100 appears to be the higher limit. Not a great command but will suffice. One more time "Thanks to everyone"

--Function requires the same name as the file
local soundPlaying = 0
local vol = 82 -- water volume 
local trigger = 3000 -- activate distance
local sound_entity = 125 --entity assigned to this lua file

function river_sound_init(e)
end

function river_sound_main(e)
  if GetPlayerDistance(sound_entity) < trigger then
	    ActivateIfUsed(sound_entity)
	    if soundPlaying == 0 then
			SetSoundVolume(vol)
	      	PlaySoundIfSilent(sound_entity, 0)
	    end
	   	else
	   	if GetPlayerDistance(sound_entity) > trigger then
	   		StopSound(sound_entity, 0)
 		end
   end
end
