I reinstalled windows 7 in my toshiba l30-114 laptop .Now i'm getting a message that no output audio device is installed.what should i do?

Uninstall and reinstall the audio driver.

For windows vista
a. Go to start
b. Type "device manager" on the start search box (windows vista).
Type "device manager" on the search for programs and files box (windows 7)
c. Expand "sound and video game controller". Usually audio driver is "realtek high definition".
d. Right click on to that audio driver and select uninstall. Do not check the box for delete. Just click ok.
e. Restart the laptop.
f. Once restarted, wait for the message that the "device software is being installed". Or go back to device manager if the audio driver is back. It should come back.
g.Test the mic.

install or update the driver of your sound card..

For no Audio output device installed message, go to device manager uninstall the audio driver. Reinstall the audio driver from either Windows update or from the manufacturer's(your Computer or Laptop) Web site.

Hi

Thanks for using FixYa. The drivers are not installed for your Toshiba notebook. You'll need to download & install the audio drivers. You can either download and install it from the drivers & utilities disk that you have got with your notebook. Or can download from this link by selecting the model number of your notebook--
