Yes, this is a limitation of the Unity Editor. Values in lists are set to their defaults (AFAIK)
What you can do is listen to the onAdd event, and manually add an item to the list:

[CustomEditor(typeof(AudioManager))]
public class AudioManagerEditor : Editor {

	private ReorderableList list;

	void OnEnable() {

		list = new ReorderableList(serializedObject.FindProperty("sounds"));
		list.onAddCallback += OnListAdd;
	}

	private void OnListAdd(ReorderableList list) {

		SerializedProperty property = list.AddItem();

		property.FindPropertyRelative("name").stringValue = "new sound";
		property.FindPropertyRelative("volume").floatValue = 1;
		property.FindPropertyRelative("pitch").floatValue = 1;
	}

	public override void OnInspectorGUI() {

		serializedObject.Update();

		list.DoLayoutList();

		serializedObject.ApplyModifiedProperties();
	}
}

If you remove the ReorderableList and just use default Unity array drawer. You should see the same issue occur. Default values not set. Unity has an issue for this: https://issuetracker.unity3d.com/issues/wrong-default-value-for-array-elements-added-in-inspector But I suspect it'll be postponed forever!
