I formatted my Toshiba Satellite L30 (PSL30L -00M00D) but no sound coming out from the speaker and head set (no audio output device ) what will I do?

from the user's manual of toshiba PSL30L -00M00D (i'm using the exact same one):

Restoring the preinstalled software from the
Recovery HDD (Depends on the model you
purchased.)
About 2.5 GB of hard disk space is reserved for the recovery partition.
When re-setting up your hard disk, do not change, delete or add partitions
in a manner other than specified in the manual. Otherwise, space for
software may be destroyed.
In addition, if you use a third-party partitioning program to reconfigure
partitions on your hard disk, it may become impossible to re-setup your
computer.
1. Turn off your computer.
2. Hold down the 0 (zero) key on the keyboard and turn on your computer.
When “In Touch with Tomorrow TOSHIBA” appears, release the 0
(zero) key on the keyboard.
3. A menu appears. Follow the on-screen instructions.
