this has not passed windows logo testing" message
This means that the driver of this device has not been checked by microsoft so it may ruin the operating system. if the product is a brand name then there should b no problem.
I assume u connected the speaker/ headphones to the green jack.
Check in the device manager that it is recognized correctly.
If it doesn't work go to start -> settings -> control panel -> sound and audio devices.
Choose the sounds tab now pick a sound that has a speaker by it. now the play below the box should be black now hit the play button. Can u hear anything?
If not try to download from the sight the newest driver.
If u need more help post the model of the audio card and the spects of you'r computer
