Check on the dell website if they have windows7 sound drivers for the optiplex280. I doubt it but if they have download and install them. If not you will have to either buy a sound card that is windows7 compatible or revert back to you provious os vista or xp

Hi,

In order to use your audio device or to hear sounds from your pc/laptop, you need to install the audio driver for it.
Usually, the drivers comes when you bought your pc/laptop.

Hope it helps.
Thanks!

Dell inspiron 8100 drivers


your audio driver is not helpful for sound card which is you install on your pc.
plaese change this driver.
all windows have different driver for different devices.
so you install the driver compatible with window vista and sound card.
