How to play my animation in real/seconds time speed without rendering?

I know that you can play the animation using alt+a, but the speed while playing is frame by frame. I wish that theres something that could play my animation in seconds speed time, without having to render it.
Can someone please help me?

nevermind! I found the answer I was looking for.
You can play your animation using the play button on the top of the Timeline window, but you have to make sure to enable the audio button for sync audio.
Found the idea in a part for playback in the book Introducing character animation with Blender By Tony Mullen
well thanks anyway.
