Soundcard on me Acer Aspire 5310: (I don't know much about soundcards, but i'll tell you as much as I can)
At the "sound menu" I can select between: Speakers
(Realtek High Defenition Audio, Standard)
Realtek Digital Output
(Realtek High Defenition Audio, Ready)
At this picture you can see it's outputs etc. very clearly

USB-Headset-Adapter
If you want, except the normal speakers, also attach a headset to your PC this stereostick is the best solution.
Speakers and Microphone can be connected easily.
You don't need another soundcard, just USB.
Highlights
Speaker-/ Headsetoutput (stereo) and mic-input.
Can also be used for Skype and other VoIP-providers.
I've already installed Asio4All V2, but I tried all the ways to connect the Discover DJ with it using my Fast Track as output 1, and using my Speaker output as output 2, but it looked very impossible.
I hope this is enough info!
thx
