Unity navigation audio toggletoggle

Hello

I created a ui image and a start button

When the image of the audio is selected via the navigation it turns grey this is good.
Also when i press enter the sprite changes to a volume button with a grey arrow in the middle.
But when i press enter again the audiolistener goes back to 1 but the sprite doesnt change back to the volume icon it does work when i press the down button so jt goes back to the other button and then back to volume and press enter the speite does change. But i wanf that you can do it whenever the slected sprite is the audio icon

Here is my script

Private sprite mutesound;
Private sprite notmuted;

If(input.getbuttondown("button")
{
If (audilistener.volume == 0)
{
  audiolostener.volume = 1;
Spritechange to nonmuted
}
If (audilistener.volume == 1)
{
  audiolostener.volume = 0;
Spritechange to muted;
}

Above code was typed on phone so not really great.

Hope someone can help

I would do something like this, (JavaScript) - pseudocode

private var muteSpr : Sprite;
private var unMuteSpr : Sprite;
private var muted : boolean = false;

function Update()
{
if(Input.GetMouseButtonDown(0))
{
muted = !muted;

if(muted)
{
muteSpr.enabled = true;
unMuteSpr.enabled = false;
GetComponent(AudioSource).Stop();
}
else
{
muteSpr.enabled = false;
unMuteSpr.enabled = true;
GetComponent(AudioSource).Play();
}
}
}
