Go to the terminal and type in:
sudo lspci
Look for lines with "audio devices" or "multimedia audio controllers". Copy
the id number in front of the line with your audio device/controller and
search for that id number at www.duckduckgo.com. A good search string is: "id
number in Linux".
Those id numbers are identifiers for hardware, if your hardware is not
supporting free drivers, chances are people are having problems with it all
over the net and posting it on forums. If there is some sort of trick to get
it to work, chances are you'll find it described in one of the forums you'll
see in the search results.
Good luck!
