This should be the correct driver link to download.

Maybe you did this already, but open the device manager, find the sound card entry, and delete it.
Shut down the pc. Power on again. The idea being to have it re-discover the sound card. If it asks you about a driver, cancel installation. Finish booting. Run the file you downloaded and saved.
Don't know if that file does the installation or just unpacks. If it just unpacks, then remember where it upacked too, and go into device manager again. Find the soundcard entry and reinstall the driver manually. Choose to find the driver yourself. Navigate to the location it unpacked to, and choose the driver from there. When you're all done, shut down again then restart.

If that does not fix it, and you tried a few times already,(it sounds like), you should face probability that it's not going to work
Good luck with it.

Which operating System is running on your Laptop? windows xp or windows vista or windows 7 or etc..? Have you tried updating the specific driver from the Device Manager? Also, what is the exact error message, it should be something like this "Windows cannot load the device driver for this hardware. The driver may be corrupted or missing. (Code 39)"
If you see similar message as shown above, then you need to delete all the entries in registry related to that specific drivers. If I am right, the sound card must be Realtek.

Let me know the details so that we can proceed forward. Thanks
Awaiting.

Toshiba laptops come with recovery disks utility built in. you can ether do it by accessing toshiba recovery disk creator. if you do not have access to your os then you have to contact toshiba support or find some one with same laptop and ask them to create recovery for you.

It is not easy. If it uses the standard round connector you need to find a replacement one (Radio Shack had the one I replaced) Then de solder the old one then solder the new one. This takes special tools you can also get at Radio Shack but if the connector is too close to small components then you will need a soldering iron with a variable heat option. Sorry long way to say.
Yes you can, on a skill-set from 1 to 10 this is about an 8
You will spend $70 (Retail) in tools for a fix the manufacturer will charge you $80 + Shipping for. Plus the manufacturer is less likely to leave you with a cold solder joint and melted plastic.
Sorry about the bad news.

The product key is associated with the MS Office 2013 software, not the specific MS Windows version of Operating System - unless the MS Office lists a minimum version of OS ie: "Windows 8.0" In this case, it would not install on Windows 7. Otherwise, you should be able to install it on Windows 7, Windows 8, or later.

How to Get Employment Security With Correct Japan Work Visa Japan is no different from other developing nations whereby grass seems greener on its side of the pasture. It attracts its fair share of foreign businesses as well as nationals seeking to work within its lands. Albeit many adhere to immigration procedures, some choose to test their limits on the basis of ignorance or defiance. By understanding the different types of work visa in Japan, it assures its foreign workers a continual stream of income with no threat of arrest and deportation. Visa simply infers the status of residence. Citizens obviously have no need of it as they automatically satisfy qualifications to freely reside in their country of birth. As for those of alien status who wish to join the local workforce, there should be a category to match one's requirement. Since most countries strive to improve the overall quality of life, professionals are generally welcomed to contribute knowledge and skill. Unskilled labor is normally not granted a visa to avoid flooding and dilution of the workforce. The visa is awarded in accordance to one's area of expertise. Supported with proof of relevant experience, it is based on the field of involvement whilst working in the country. In the event one's work scope changes from one expertise to another, it is essential to apply for a visa under the new circumstances. Different types of work visa in Japan also apply to foreign companies seeking to conduct local business. Domestic companies based abroad wishing to set up a local point of presence need to provide supporting documents to justify internal transfer of foreign workers. Governmental staff for diplomatic duties is assigned a category for legal residence. Over and above the general groupings, designated activities also garner approval from the authorities. Domestic service for non-native residents and citizens of certain nations on working holidays fall into this category of working visa. This, by no means, is the end of the list as it is best to consult the authorities on which visa serves best.Click Here For More Details: http://japanjobandvisaservice.com/blog/change-your-luck-when-apply-work-visa
