vexpress: No sound in Ubuntu

[Paul Larson]

In the 12.05 release image testing for vexpress:

I'm not getting any kind of sound through headphones from any of the plugs.
In the sound settings menu, I see the following options:
LFE on Separate Mono Output / No Amplifier
LFE on Separate Mono Output / Amplifier
Analog Mono Output / No Amplifier
Analog Mono Output / Amplifier

There's no option for the headphones I plugged in though, and when I try rhythmbox, or other methods such as test sound from the sound properties, I get no sound

This is probably due to bug 1009389

I've downloaded the 12.06 release and if I select this audio device, I get sound out of the green audio jack:

LFE on Separate Mono Output / Amplifier

The default options don't give sound on the board.
