Touch vibration in unity(C#)?

Hi,

I just keep crashing my game trying out different ways to enable touch vibration, does anyone know how to do it correctly in Unity 5?

Start()  HapticsClip = new OVRHapticsClip(VibeClip);

RHit()   OVRHaptics.RightChannel.Preempt(HapticsClip);

^ In this example VibeClip is less than a second long audio clip

^This crashes unity. so does trying 

OVRHaptics.Channels[1].Mix(new OVRHapticsClip(VibeClip));

Here's an example you can use to play a sound and corresponding vibration on contact.

using System.Collections.Generic;
using UnityEngine;

public class PhysicsSound : MonoBehaviour
{
	public bool useHaptics = false;
	public bool useSound = true;

	public OVRInput.Controller controller;

	private AudioSource cachedSource;
	private OVRHapticsClip hapticsClip;
	private float hapticsClipLength;
	private float hapticsTimeout;

	void OnTriggerEnter(Collider c)
	{
		if (useHaptics)
			PlayHaptics(c);

		if (useSound)
			PlaySound(c);
	}

	void OnCollisionEnter(Collision c)
	{
		if (useHaptics)
			PlayHaptics(c.collider);
		
		if (useSound)
			PlaySound(c.collider);
	}

	void PlayHaptics(Collider c)
	{
		var source = c.GetComponent<AudioSource>();
		if (source == null)
			return;

		if (source != cachedSource)
		{
			hapticsClip = new OVRHapticsClip (source.clip);
			hapticsClipLength = source.clip.length;
			cachedSource = source;
		}

		if (Time.time < hapticsTimeout)
			return;

		hapticsTimeout = Time.time + hapticsClipLength;

		if (controller == OVRInput.Controller.LTouch)
			OVRHaptics.LeftChannel.Preempt(hapticsClip);
		else
			OVRHaptics.RightChannel.Preempt(hapticsClip);
	}

	void PlaySound(Collider c)
	{
		var source = c.GetComponent<AudioSource>();
		if (source && !source.isPlaying)
			source.PlayDelayed(0.1f);
	}
}

VRDave, thanks for the code sample, and strange, I don't get any vibration when I try. I'm on all latest Unity & Oculus sdk, did something change in the meantime or am I doing something wrong?
