Script pressing play "speaker" button in audiosuite window

Hi,

I am trying to write a script to press the listen/play "speaker" button in an audiosuite window. I tried the following script with different names but I can't figure out if this button have a name or it's just the logo. Or if there is another way around this.

sf.ui.proTools.firstAudioSuiteWindow.buttons.whoseTitle.is('').first.elementClick();

Thanks !
