How to adjust the volume using the slider?

Question

Unity

I am adjusting the volume of music and effects, I found several video examples, I repeat as there, but the result is different.

public AudioMixerGroup Mixer;

 public void ChangeVolumeMusic(float volume)
    {
        Mixer.audioMixer.SetFloat("MusicVolume", Mathf.Lerp(-80, 0, volume));
    }

I stuck the method to the slider, but when I start to change the slider even a little, the sound stops immediately, but it works fine on the video, what could be the problem?

You should at least look at the documentation for what Mathf.Lerp is before blindly blindly copy-pasting the code from the video: https://docs.unity3d.com/en/2019.4/ScriptReference... . You absolutely do not need lerp here, because if you set t less than one, then when you try to set the volume to 100 (or another number), you will have it less than 100. And if t is equal to 1, then there is no point in linear interpolation. replace with just volume. Mathf.Lerp(-80, 0, volume)
