In the Karting tutorial, it says to delete all calls to “playsound”
What exactly does this mean?
Here is the script containing “playsound”
What do I delete? All of it?
```
void PlaySound(AudioClip sound)
{
if (!sound)
return;
if (!m_AudioSource)
{
m_AudioSource = gameObject.AddComponent();
m_AudioSource.outputAudioMixerGroup = AudioUtility.GetAudioGroup(AudioUtility.AudioGroups.HUDObjective);
}
m_AudioSource.PlayOneShot(sound);
}
```

This is the creation of the function `PlaySound`. A “call” would be any time this function is used in other parts of the Unity project. You need to do a search in all scripts for any time the `PlaySound` function is used and delete those lines. You should be able to do a search across the entire project in your preferred IDE.
