I am also a new person to Linux. Im 2 days into the Linux scene and are having a blast! I have no idea about computer programing and know nothing about Linux apart from what im reading and writing down in my notebook
My first Linux issues was yesterday with my sound card too. I was using Ubuntu at the time (trying out different Linux dists. and I really like Ubuntu and Mepix so far). To fix my problem i had to:
At the terminal, type in alsamixer.
This should bring up a volume control screen with sliders and small boxes with the letters MM inside.
Now, my problem was that my sound card was in Digital mode. All i did was use the Right Arrow key and scrolled to where it said Analoge. I raised that slider bar to full. Where the small box above the box <audigy A> is with the MM letters inside, i hit M. What this did was turn on my sound card and everything worked fine. That box with the MM in sound be highlighted Green when its activated.
Hope my noob-ness can help you
