Speaker icon has a Red X on it, "no audio output device is installed".

Hi,

Generic Sound Troubleshooter for Vista and should work on Windows 7 as well.

Control Panel - Device Manager - SOUNDS - look for HD Audio - Mine says RealTek High Definition Audio 

Write down description make and model - double click on it - drivers tab - write down version. Now

Click UPdate Drivers which may not do anything as MS is far behind certifying drivers. Then RIGHT

CLICK on it and UNINSTALL - REBOOT - this will rebuild the driver stack.

1st go to system maker's site and look for latest driver Download - SAVE - go to right click on and RUN AS ADMIN

(This is your fallback.) REBOOT after each driver installation.

NOTE : Sound driver often rollback so check the version after installation and the reboot to see if the version you

installed is there, if not repeat - reboot until it is. It can take several tries depending on how many rollbacks it

does.

Then do same for Device Maker's site.

Manually look at manufacturer's sites for drivers - and Device Maker's sites.

Hi,

Toshiba Support probably has drivers for Windows 7 and updated Vista ones also as well as many of the

drivers will be updated and available at the Device maker's sites.

Click on Product Support on upper left and navigate to your model.

Update your drivers manually by looking at System maker and Device maker's sites.

This is my generic how to for proper driver updates :

This utility makes it easy to see which versions are loaded :

DriverView - Free - utility displays the list of all device drivers currently loaded on your system. For

each driver in the list, additional useful information is displayed: load address of the driver, description,

version, product name, company that created the driver, and more.

http://www.nirsoft.net/utils/driverview.html

For Drivers check System Maker as fallbacks and Device Maker's which are the most current.

Control Panel - Device Manager - Display Adapter - write down the make and complete model of your

video adapter - double click - Driver's tab - write down the version info. Now click UPdate Driver (this

may not do anything as MS is far behind certifying drivers) - then Right Click - Uninstall - REBOOT

this will refresh the driver stack.

Repeat that for Network - Network Card (NIC), Wifi, Sound, Mouse and Keyboard if 3rd party with their

own software and drivers and any other major device drivers you have.

Now go to System Maker's site (Dell, HP, Toshiba as examples) (as rollback) and then Device Maker's site

(Realtek, Intel, Nvidia, ATI as examples) and get their latest versions. (Look for BIOS, Chipset and software

updates at System Maker's site while there.)

Download - SAVE - go to where you put them - Right Click - RUN AD ADMIN - REBOOT after each installation.

Always check in Device Manager - Drivers tab to be sure the version you are installing actually shows up. This

is because some drivers rollback before the latest is installed (sound drivers particularly do this) so install a

driver - reboot - check to be sure it is installed and repeat as needed.

Repeat at Device Makers - BTW at Device Makers DO NOT RUN THEIR SCANNER - check manually by model.

Manually look at manufacturer's sites for drivers - and Device Maker's sites.

If you update drivers manually then it is a good idea to disable Driver Installations in Windows Updates,

this leaves Windows Updates ON however it will not install drivers which will usually be older and cause

issues. If Updates suggests a new driver then HIDE it (Right Click on it) and then go look for new ones

manually if you wish.
