How to play a Sound at a certain frame?

Hello. I have a very simple .fla where you press X times a button it goes to frame 2.

I would like to play a sound every time I reach frame 2, but I'm a bit confused with the code. I read some tutorials, but they were about 2.0 and the 3.0 ones were poorly explained.

Let's assume I imported a sound named 'ping.wav'. What do I need to do to play that sound on frame 2?

Thanks.

You can import the sound clip into your library and select a frame, then in properties under "sound" just choose that sound and set the sync to "start".

If you want to do it with code, take a look at the intro to sound tutorial over at gotoAndLearn.com.
