Disabling button's sound when button is disabled

[wallabie]

How to disable the sound on a button when button.enabled = false ?

ATM, the button is disabled but it still reacts to clicks.

Disable the UIPlaySound script.

If I had 20 Go's that are listening to the onclick event from the button, is there a way to stop the button from firing a onClick event when the button is disabled?

UIPlaySound script doesn't listen to the button's On Click. It listens to the generic OnClick event, which comes from the event system. It's a stand-alone component and is not related to the button itself. Here, I've modified UIPlaySound to check the button.
