I'm having a weird error and maybe it's not related to my code. It doesn't happens all the times..

Output log: hastebin.com/idiruzolek.avrasm

MicroUIWindowOptionsAction.cs

public void VolumeChanged()

{



	Toolbox.Instance.VolumeSFX = SoundVolumeScrollbar.value;

        Toolbox.Instance.VolumeMusic = MusicVolumeScrollbar.value;



        PlayerPrefs.SetFloat("SoundVolume", SoundVolumeScrollbar.value);

        PlayerPrefs.SetFloat("MusicVolume", MusicVolumeScrollbar.value);


	if (VolumeListener != null)

		VolumeListener.VolumeChanged();

	else

		VolumeListener = FindObjectOfType<VolumeListener>();

}

VolumeListener.cs

using UnityEngine;

using DarkTonic.MasterAudio;



public class VolumeListener : MonoBehaviour

{



    internal MasterAudio MasterAudio;



    void Awake()

    {

        MasterAudio = GetComponent<MasterAudio>();

    }

	

    public void VolumeChanged()

    {

        if (!MasterAudio.SoundsReady) return;

        MasterAudio.PlaylistMasterVolume = Toolbox.Instance.VolumeMusic;

        MasterAudio.MasterVolumeLevel = Toolbox.Instance.VolumeSFX;

    }

}

I can't replicate this scenario too. It's happening with a tester.. Also, please note that on VolumeListener I'm getting the MasterAudio component without need it. I'm giving you the exact code of the version that is throwing the error

You're going to need to send me a sample project that reproduces the error. Please see the stickied post on bug reporting at top of this forum. I don't know when said code fires and lots of other things.

Sure, Will try to rip the project.

Meanwhile, I could reproduce 100% of time. Items to be considered:
1) It doesnt happens on editor, only on standalone versions.
2) With a little debug, I found out that when changing volume, somewhere it force-calls Awake() On PlaylistController and:
2.1) Inside Awake(), useGUILayout is NULL(!?), throwing the null exception error.
2.2) If I comment the useGUILayout, the next error happens on line 168, returning ZERO components. Then I give up

var audios = GetComponents<AudioSource>();
PS: The above scenario happens only on standalone AND when I change scenes. For example: I start the game and at the mainscreen there is an options dialog with scrollbar, change volume, no errors. Go to next scene, Back to mainscreen, open dialog, change volume, Error.

I'm not sure where the error would be. Are you on the very latest version of Master Audio?
