Ok, first you didn't read the big red information request above the question field... so, now I have to assume...I assume that you have a PC, and so, you need to know that you need to go to :
Start menu>control panel>sound>playback.... there you should find the Audiobox installed and something called "realtech high definition audio device...( you will also note at the top, tabs for Recording, Sounds, and communications...) If you want to have the playback through the computer speakers, or headphone jack, the Realtech High definition audio need to be selected as the 'default' device'. if this is selected then the audio will be routed to the computer sound ports, if you DE select that, and select the Audiobox, your sound will be routed to your audiobox device. remember, that the device you want to have the audio go through MUST have the green check by it!
