I fixed the sound on my Vostro A90! The volume control now has a Speaker track and sound comes out of the speakers.
I tried "sudo apt-get install padevchooser ubuntu-restricted-extras", adding my user to pulse, pulse-access, and pulse-rt groups, and fiddling with the PulseAudio Device Chooser, but I'm pretty sure that didn't matter and what actually fixed it was:
sudo nano /etc/modprobe.d/alsa-base.conf
Add a line at the bottom "options snd-hda-intel model=dell" and reboot. No Ubuntu startup sound, but Rhythmbox plays music through the speakers (or headphones instead if I plug them into the jack).
