Volume Slider not working as expected

[wagman1967]

Problem: The volume doesn't seem to change after about the first third of the bar. In other words, if I set the slider all the way to the left, the volume is muted. As I start moving the slider to the right, I can easily tell it is getting louder...but it seems to get the loudest when I am only about a third of the way toward the right (if this were a volume knob that went from 0 to 10...it would be its loudest about 3). I cannot distinguish a volume change in the last two thirds of the bar.

I am using the slider component, and have the maximum set to '1', the snapInterval set to "0.01", and the value set to '1'.

I am using the follow code:

import fl.events.SliderEvent;

import flash.media.SoundTransform;

var voltransform:SoundTransform = new SoundTransform();

Slider.addEventListener(SliderEvent.THUMB_DRAG,changevol);
function changevol(event:SliderEvent):void{
voltransform.volume = Slider.value;
SoundMixer.soundTransform = voltransform

}

Any ideas why this happens? Or a fix?

Thanks

your max slider value is probably 10 (or, at least, greater than one) so you're going to get to the max volume (1) pretty quickly.

use trace(Slider.value) to confirm that's the problem then assign Slider's max value to be one.

[wagman1967]

I am a novice to this, but what I have read suggests the maximum value needs to be set to "1". I have tried "10" and "100", but I end up with distortion when playing an mp3.

I am not even sure how to use trace(Slider.value)

Thanks

change the instance name of your slider to slider_sp in the properties panel.  then use the following code:

import fl.events.SliderEvent;

import flash.media.SoundTransform;

var voltransform:SoundTransform = new SoundTransform();

slider_sp.minimum=0;

slider_sp.maximum=1;

slider_sp.addEventListener(SliderEvent.THUMB_DRAG,changevol);

function changevol(event:SliderEvent):void{
voltransform.volume = slider_sp.value;
SoundMixer.soundTransform = voltransform

}

Thanks again for helping.

When I just change the instance name and replace the code, I get the same effect that I have been getting.

Do I need to change any of the values that are set in the properties box? I tried leaving them as I have them listed above, and I have tried with them zeroed out and still get the same thing.

This is not a huge deal, as I was trying to add the slider to an existing soundboard I created a few years ago. I was updating some of the selections and thought I would try to add a volume control.

I don't know if it makes a difference, but I do not have any of the songs imported. I just have the buttons point to a local directory (I only use this swf file locally) of songs.

I just use this code for the buttons (edited for each song):

var fl_ToPlay_3:Boolean = true;

function fl_ClickToPlayStopSound_3(evt:MouseEvent):void

{

    if(fl_ToPlay_3)

    {

        var s:Sound = new Sound(new URLRequest("C://GAME DAY MUSIC/ARE YOU READY FOR SOME FOOTBALL.mp3"));

        fl_SC_3 = s.play();

    }

    else

    {

        fl_SC_3.stop();

    }

    fl_ToPlay_3 = !fl_ToPlay_3;

}

show the slider code you're using.

[wagman1967]

Original is what I listed in first post...

After renaming the instance, I just copied and pasted what you told me above.

[kglad]

drag the slider from one end to the other and paste the trace output from

import fl.events.SliderEvent;

import flash.media.SoundTransform;

var voltransform:SoundTransform = new SoundTransform();

slider_sp.minimum=0;

slider_sp.maximum=1;

slider_sp.addEventListener(SliderEvent.THUMB_DRAG,changevol);

function changevol(event:SliderEvent):void{
voltransform.volume = slider_sp.value;

trace(slider_sp.value)
SoundMixer.soundTransform = voltransform

}

then the slider is working as expected.

do you have a snapInterval defined (greater than 0) so you can drag between the extreme left and right?

[wagman1967]

Yeah...that is currently set at 0.01

I guess the slider is working as expected, but it is not doing what I expect.

[kglad]

the volume of all your sounds will vary between 0 and 1 as you move the slider.  what do you expect?

[wagman1967]

I would expect the volume to be mute when the the slider is all the way left (0) and as loud as it can be when all the way right (1)...and about half as loud is it can be when in the middle (.5)...and so on.

It is mute at 0, but as I slide to the right, it quickly gets to its loudest point about a third of the way to the right and remains there the rest of the slide.

If I move the slider along the right two thirds of the bar (either direction), the volume remains steady at max volume.

Over the left third, it works like I would expect it to over the full length of the bar...it incrementally lowers as I move left and incrementally raises as I move right...but anything further right that the left third is max volume.

try a different sound.  maybe there's something wrong with the one you're using now.

[wagman1967]

I have tried it on about 10 songs already...same result.

I will try it on a different computer, later and see if it might be the culprit.

Otherwise, I can live without it (have for years, anyway).

[kglad]

the code i suggested works for me and i don't see the issue you're describing.

[wagman1967]

Well, I feel that I have wasted your time.

I tried it on another PC, and it works like a charm.

So, I need to go hunting the reason for that.

The one I was using it on is a brand new, top of the line, Lenovo X1 Carbon Thinkpad, running Windows 8.1...no joy.

Just tested on desktop running Windows 7...worked a charm.

Go figure.

I truly thank you for your time and patience.

[kglad]

you're welcome.
