I install already my emachine d725 audio driver but its not work..i dnt know what to do i have a original drivers cd of emachine notebook..tell me what can i do

Only of the CPU is a 64Bit CPU

Drivers are not independent entities they are related to the the platform that you are using as in your case its Ubuntu if you change the platform you may require to have a separate set of audio drivers.Also in most of the cases there is no need to install teh drivers manually as the latest Operating Systems can detect and install them automatically for you but in case there is an issue the drivers installers are usually provided by the manufacturers but I suggest you download the latest from the manufacturer's website.

This maybe a driver problem. You should try searching for new drivers on the internet. Try DriversHQ.com
Hope this helps

Good luck to you.

SOLUTION #1: If you have a driver CD that came with your eMachine, look for the audio folder on the CD. If there is a "setup" program inside this folder, then run it. SOLUTION #2: Start, Control Panel, System, Hardware, Device Manager, right click on sound device, choose Update driver, install from list, don't search, have disk, browse to the audio driver location on the driver CD, then okay it. SOLUTION #3: Download the file from the following URL, unzip it, then run the SETUP program inside the folder. http://downloads.emachines.com/drivers/audio/T1140_50_Audio.zip
