Is it Possible to Preview Sound While Scrubbing the Timeline Using Hotkeys?

If I have a sound in my timeline, I can scrub through the timeline by dragging the red box and it will preview the sound that plays on every frame. However, I use hotkeys set to scrub through my timeline (, & .), and when I use them, the sound does not in fact preview. Is there a way to set up my hotkeys so the sound will in fact preview?
