adobe audition only shows two speakers after installing 7.1 USB external sound card

I am connecting a startech 7.1 usb external sound card to my computer (windows 7) and trying to playback a 4-channel sound from adobe audition. In adobe audition, I set the output hardware to be my USB multi-channel speakers. However, when I was mapping the audio channels, I only got two speakers available. I was expecting 8 speakers because my external sound card has 8 channels. Am I missing anything?

    I am afraid that this device won't do what you want it to. Unfortunately, like a lot of theses low price USB audio adaptors, they do not supply discrete multichannel outputs. So they won't work with Audition except, as you have found, as a basic 2 in 2 out device. The surround capability is only available for already encoded audio that comes off disc or a media player. So it will decode Dolby AC3/DTS and other similar already encoded audio files but not stream multichannel .wav files from a DAW.

    What external audio interface have you got? Have you downloaded any ASIO drivers from the manufacturers site?

    Hi, thank you for responding. I am actually not sure the exact interface it uses, this is its website: USB Audio Adapter External Sound Card | USB Audio Adapters | StarTech.com

    I have ASIO on my computer, but when I chose "ASIO" as the Device class, I don't see my USB multi-channel speakers show up... I have minimal experience on dealing with sound outputs, so I might be completely off...
