Before you get bogged down with the launchpad, try to get sound out of Ableton Live on it's own. The Launchpad and Ableton work well together, but neither is a requirement of the other.
Load up a sample into clip view. If you do not understand what this means, then read through some documentation that came with your Launchpad, or download and read the Live Manual. Press play on the clip. Do you see your meters bouncing now? Do you hear audio? If meters are bouncing, specifically on the "Master" channel, and not blue, than you have an issue with your soundcard/speakers/headphones/volume level/etc.
If your Master Channel is bouncing, but is blue, it is likely trying to use an audio interface that is not available.
First, go to Preferences > Audio
Check the selections for "Audio Output Device" -- does it make sense? Are you using an external soundcard, or just whatever is available? Click on "Output Config" and make sure some of these options are enabled (yellow).
Then go back to Live's mixer, and make sure the Master Out selection is one that makes sense.
If you still do not have audio, then you need to sit down with the manual and read to understand setting up Live, and check your soundcard to make sure other sounds play from other programs.
Now that you have audio coming out of Live:
Go into preferences > Midi / Sync > And select Launchpad from the Control Surface List. Make sure to also select it for Input and Output.
From here, you can do any of the standard Launchpad stuff. Load up a drum rack with some samples and start banging away, trigger clips, play synths, etc. Read the quick start guide that came with the Launchpad to better understand what it's capable of.
Good luck, and please remember to write in complete thoughts with punctuation when you want someone else to read your questions.
