Toshiba, No sound until after waking from hibernate/suspend

Question

From the title my question is obvious. I have a Toshiba Satellite model L655-S5165
When I boot the machine there is NO sound at all unless I use the head phone jack,
but after hibernating or just closing the lid and waking it up then I have working sound out of the speakers
for various amounts of time until it stops working again. The head phone jack works all the time without fail.
Any Idea what may be going on here?

When you say there is no sound, what applications have you tried?
Assuming that you have tried more than 3+ applications including iTunes, flash videos like youtube and some other applications. It might be a good idea to reset the PRAM and SMC
SMC RESET
Shut down the computer.
Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.
On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
Release all the keys and the power button at the same time.
Press the power button to turn on the computer.
  PRAM RESET
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
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 second time.
Release the keys.
