Audio disappears after adding an effect in VS Pro X5

[Keithchr]

If I add an avi clip into the timeline, I can hear the audio in both clip and project playback.
However, once I have added an effect (any effect), the audio cannot be heard in clip playback -
it can only be heard in project playback. If I remove the filter, the same thing still happens - no audio in clip
playback - only in project playback.
Am I doing something wrong or is this supposed to happen?
Thanks for any help.

That's the way it's designed. You have to close the Attribute tab by clicking on the Video tab.

Edit: Deleted part about closing the Options window.
