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.
