Though it works with windows 7, according to the website, the software that came with it does not.

Sorry, Kworld does not list any Win 7 drivers for that card.

Your computer's sound card maybe at fault

if using Windows make sure to check the Sounds and Audio device Properties by Right clicking the speaker icon on the right side of taskbar. Check all tabs for Recording settings, there may be recording tests on some pages...check Advanced rbuttons for recording settings.
note settings prior to modification so you can change them back if needed.

i bought vs-usb 2800d but the instalation Cd broke, i could not instal the programme wht should i do?

The sound enters the PC through the 'line' input audio connection. In the audio panel controls, ensure that the line input is enabled, and the gain is not zero.
