You can download the driver from this link:
On the left side of the page there is a link "Driver & downloads". Click on it, then on the middle area of the page, under "SELECT PRODUCT" you will select "Notebooks".
A new menu appears, select "LIFEBOOK".
A new menu appears, select "LIFEBOOK E".
A new menu appears, select "LIFEBOOK E8410 (Intel Graphic)" or "LIFEBOOK E8410 (Intel Graphic)". (Makes no difference, since the audio card is the same ALC262 in both versions).
After this, there appears a list with operating systems available. Select the one you are using, then select "Audio".
I would suggest to install first the "Chipset" driver from the same list, then restart the computer and after restart install the audio driver.
