Hi and welcome.
I am not sure if your device is a PCIE card or an external USB.
See if my Tutorial on how to get a SoundBlaster Audigy RX helps you.
For starters I would advise you install all ALSA packages, (except those for JACK and OSS) which will require you to install Synaptic Package Manager, available in Software.
Also install qasHctrl, qasTools, qasMixer and one other (just search for qas in Synaptic Package Manager, and all 4 packages will be shown).
Lastly, be sure to install Audacious Audio Player.
Here is the link to the tutorial:
Be sure to read the entire thread, not just the first post as it also explains settings for Audacious.
