My sound card not work in my pc win 7

You could, drivers are based on manufacture. Like Realtek is a common maker of audio chips, and sometimes distributors use a popular motherboard.
You may have plateaued at Vista, by try the Troubleshooting Compatibility with Vista 64 drivers before you roll it back.

BTW - This happened to me with Win 8.

the win xp drivers are not compactable with win 7 you will have to download the drivers for win 7 to work fine

download the drivers for win 7 because the software which is provided not supporting win 7.
or go through this link for drivers for win 7 http://www.dl4all.com/as2/tag/creative+sound+blaster+5.1vx+model+sb1070+driver+for+windows+7.html

Here is only drivers for win xp.

Install a soundcard in the pci socket and make sure the driver is supported for your windows system.

hello sir my pc pent 4 win 7 & sound card not work crectly

Go to the chipset manufacturer and see if they have an updated driver for the sound card. It will come up as an unsuported driver but sometimes they are quicker to get updates than the manufacturer of the sound card.

This is a link to E-Mu for info for the 1212M sound card. Unfortunately Win 7 is not listed. Does Win 7 offer running a program/drivers in compatibility mode? Just a thought.

If you mean the xp/vista/win 7 installation cd's then you have to make your own. The manual that came with the pc will give you the information that you need. If it's xp it will be 1 dvd, vista needs 2 dvd's or 7 cd's, i'm not sure about win 7. As for the sound, what you could do is to drop the drivers for the sound card and reboot the pc, this will refresh the connection between hardware & software. To drop the drivers you need to go to start>>right click my computer>>properties>>hardware tab>>devise manager>>click on + sign next to "sound, video & game controllers & look for the sound card. Do not remove codecs, just the sound card then reboot.

Hope that works for you!!
