Question Audio Mixer Slider doesn't work in Android

So I found a question with the same problem as me, but sadly it wasn't answered. Anyone can help please?

Basically the sliders that modify the Music and the Audio FXs work when I play in the editor mode in my computer, but not when building for android. I create the exposed parameters in the Audio Mixers that control the volume etc. As I said, it works when I hit play button, but not at all in my phone. This is the code:

Code (CSharp):

1.  using UnityEngine;
2. using UnityEngine.Audio;
3. using UnityEngine.UI;
4. public class VolumeSliders : MonoBehaviour
5. {
6.      public AudioMixer mixer;
7.      [SerializeField] private string audioMixerParameterName;//I create a PlayerPrefs float with the same Key
8.      private Slider slider;
9.      private void Awake()
10.      {
11.          slider = GetComponent<Slider>();
12.      }
13.      private void Start()
14.      {
15.          slider.value = PlayerPrefs.GetFloat(audioMixerParameterName, 1f);
16.      }
17.      public void SetVolume(Slider slider)
18.      {
19.          mixer.SetFloat(audioMixerParameterName, Mathf.Log10(slider.value) * 20);
20.          PlayerPrefs.SetFloat(audioMixerParameterName, slider.value);
21.          PlayerPrefs.Save();
22.      }
23. }

Is there any fix or workaround this issue?
Thank you

 

Thank you for your answer The_Island. My unity version is 2020.3.14f1, so maybe it has been fixed in newer versions.

With respect to SetVolume, no I don't ever call it, could you please elaborate more on how to do it? I thought that just by calling:

mixer.SetFloat(audioMixerParameterName, Mathf.Log10(slider.value) * 20);

it would be enough to set the volume.

 

Ohh yeah, sorry I misunderstood. I forgot SetVolume was my method, I thought it was a bult in Unity one. Yes of course I call that function exactly as you showed me. As I said, it works perfectly fine in Editor mode (I think this is important to notice). I tried what you suggested, updating to Unity 2021 LTS, and removing audio mixer as a parameter as I call it already in Awake, but nothing, the problem still persists, basically when I build it for android it stops working.

Do you know any workaround or other way of implementing a volume slider with AudioMixer? Something else that I may try? Thanks!
