Use PlayerPrefs to store desired volume in settings scene and when load it in game scene.

// somewhere in your settings scene
PlayerPrefs.SetFloat("SFX Volume", mySoundVolume);

// script on some game object in your game scene
using UnityEngine;

public class SettingsLoader : MonoBehaviour
{
	// you should drag your AudioSource component
	// on this field in inspector
	public AudioSource audioSource;

	void Start () 
	{
		audioSource.volume = PlayerPrefs.GetFloat("SFX Volume", 1f);
	}
}

You are doing DontDestroyOnLoad(gameObject); in the awake function. So that means your game object is not destroyed when you load another scene.

To lower the volume, create a function:

function reduceVolume()
{
audio.volume = 0.3f;
}

And call it like you would call any other gameobject function.
