How can I determine if property was set to 'None (Audio Clip)'

Hi to All,

I have a MonoBehaviour class attached to to a gameObject. The class has an AudioClip public member variable which is visible in inspector:

public AudioClip TestAC;

In the inspector it set to ‘None (Audio Clip)’. I am trying to check in the Start if there is a valid AudioClip provided, and if not I would like to set a default clip.

Suprisingly checking the TestAC variable against null results false.

How can I determine if my TestAC variabe was set to ‘None (Audio Clip)’ in inspector? (using C# code)?

Thx for answers
