Comment 67 for bug 893210

Hi, I am also trying to get internal speakers to work on Dell OptiPlex GX620 (model no.: DCCY). External speakers work, however internal speakers are not even listed in PulseAudio Volume Control (and there is no sound). The internal speakers worked on previous OS (Windows XP).

do you mean your desktop have stereo internal speakers since ad1981b only has three output

line out
hp
mono out

and your dell gx520 seem have hp at front and line out at rear

Small error on my part: I have OptiPlex GX520, not GX620. Should be similar though. Attaching my alsa-info.
