Hello Christopher,
thanks for the comment, but I don't think it's BIOS related.
Verified again on 201202-10592 with 12.10 + update (3.5.0-45)
Volume can be controlled by hotkeys, sound could be played normally.
But the output device section still empty.
With further investigation, it might be caused by pluseaudio
an output device (Built-in Audio Analog Stereo) will appear with this command:
pactl load-module module-detect
please find attachments for "pacmd list-sinks" results before and after
this pactl command.

Title:
[Dell Vostro 2420] Internal speaker does not show up in "Sound
settings"
Status in “pulseaudio” package in Ubuntu:
Confirmed
Bug description:
CID: 201202-10592
This is a SRU system which is running 12.10 (3.5.0-34-generic
#55-Ubuntu)
The internal speaker does not show up in "Sound settings"
But I can still play sound through the internal speaker normally (like
pressing the volume button)
And if you connect a headset to it, there will be a "Headphones" option
available in the "Play sound through" list
