Public bug reported:
The speakers work, but the headphones do not, on Gutsy and Hardy beta.
Plugging in a headphone just mutes the speakers. On Gutsy, I've tried
quite a few things to get it working, including installing oss and
pulseaudio, to no avail. I remember the best I got to getting the
headphones working was while running osstest:
Sound subsystem and version: OSS 4.0 (b1011/200712200355) (0x00040003)
Platform: Linux/i686 2.6.22-14-generic #1 SMP Tue Feb 12 07:42:25 UTC 2008

*** All tests completed OK ***
In the first test, only the speakers play. In the second test, only the
headphones play! In the third test, nothing plays.
I would have tried osstest in Hardy beta except osstest isn't installed.
Here's some output from my Hardy beta installation, on which I did not
mess with the sound system:

Here's some output from my Gutsy installation, on which I messed with
the sound system a lot, including installing OSS and then pulseaudio:
