I have searched quite a lot looking for a solution. Here is the sound info from the terminal.
Audio device: Advanced Micro Devices, Inc. [AMD] FCH Azalia Controller (rev 01)
I believe the problem is that my computer has the DVI-D connector that requires an adapter to connect an HDMI cord. The connector doesn't output audio so I bought a 3.5mm stereo to red/white rca cable for the audio.
The audio worked with a previous install of Ubuntu, sorry I can't remember the release. (Long story I was trying to get Win 8 and Ubuntu to work together...that's another F^&%king nightmare)
Please Please help. I have been using Ubuntu for about 5 years and other than when I need to use a couple specialty hardware items I never even bother with Windows.
