This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

Are you not getting any display at all? Do you have garbled video? – Dean Howell Jun 18 '12 at 18:48
For the graphics question see the link above. for subwoofer question i suggest you to ask another question. – Anwar Shah Sep 17 '12 at 7:34

Install Mesa-Utils by running these commands:

sudo apt-get update
sudo apt-get install mesa-utils

Then it will be detected.
