* Show unconnected pins
Your BIOS is responsible for setting up what pins on the codec that are
actually connected to something and which ones are not. Sometimes BIOS is
buggy, and will not show all your jacks. If you have a jack your BIOS says you
haven't, you can try enabling random pins and see if it works.
* Advanced override
This is for the experts only. It makes you select each configuration field
individually, instead of just a few predefined values that make sense. Note
that most combinations here are invalid in one way or the other, so you should
probably not mess with this unless you have read and understood the
"Configuration Default" section of the HD Audio specification. (Which, at the
time of this writing, is available here:

Title:
[Aspire 9800, Realtek ALC883, Internal Speakers] Playback problem
Status in “alsa-driver” package in Ubuntu:
Confirmed
Bug description:
No sound on internal speakers. Headphones out works fine. Last working
kernel version is 3.2 with options snd-hda-intel model=acer in alsa-
base.conf, but later versions won't work with any possible model =
values (and without it). It seems that it is kernel bug because after
kernel downgrade to 3.2 version I got sound working.
