Hello and thanks for using

When you start Skype your sound stops working and a restart brings it back until you start Skype again?

Let me know if that is the question. Please also let me know the following:

What OS are you running? ie. 10.7.2 or 10.8.2

If you click on the Apple icon in the top left and choose about this mac. It will tell you the version number.

Also let me know what it says next to processor and what type of computer it is. Laptop/imac

Please do the following:

Shut down the computer.

Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.

Turn on the computer.

Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.

Hold the keys down until the computer restarts and you hear the startup sound for the third time.

Release the keys.

I would also reinstall Skype. Go to the following link and download
