Comment 38 for bug 1332900

I should also add the Sub-woofer isn't present in the volume control
Only analog stereo output
and Analog Surround 4.0 but only plays stereo when texting
The is also "no" sign of my Nvidia cards in the sound settings either

There are 3 output Jacks on the left side of laptop
The Jack closest to the screen does nothing no sound and no Mic

The one in the middle has sound and Mic

The one at closest to me the front end has sound and Mic too

This "alsa-info.sh" does nothing either when posted in the Terminal
I had to search the net I found this and it worked
wget -O alsa-info.sh http://www.alsa-project.org/alsa-info.sh && chmod +x ./alsa-info.sh && ./alsa-info.sh

Why do those commands do nothing ?
anyway the Alsa info is in attachments
