That's a completely different checkbox and different option than what I'm talking about. That's for James' request for core audio and that's fine. My option is for selecting the HD audio track/s for a selected language/s. So if you select english as your default language and the HD Audio ONLY checkbox is checked, it will only select HD audio track/s that are english. Think of the checkbox I'm asking for as a global enhancement filter. What you're asking for is per track. That's a whole different issue.
