Anybody have all 5 speakers (front l+r,rear l+r and woofer) working? Currently only the front two (front l+r) are working. I'm running a fresh install of 12.10. Headphones work fine though. Doesn't matter which program is producing audio either.

The subwoofer and rear speakers are not detected in Debian. You need to correctly assign the pins using hdajackretask. To install hdajackretask execute following command in terminal

sudo apt-get install alsa-tools-gui

now run the hdajackretask using terminal. A window will open with many options. Select the proper "Codec" and check the "Show unconnected pins" and now change the pins accordingly.

0x0D -> Internal Speaker

0x0F -> Internal Speaker (Back)

0x10 -> Internal Speaker (LFE) #This is the subwoofer

Now click on "Apply". To make the changes permanent, click on "Install boot override".
