Bug Description
The speakers work, but the headphones do not. Plugging in a headphone just mutes the speakers.
This occurs with Gutsy and Hardy. No tested yet on Intrepid.
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/
Platform: Linux/i686 2.6.22-14-generic #1 SMP Tue Feb 12 07:42:25 UTC 2008
*** Scanning sound adapter #-1 ***

*** 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:

I confirm this bug. Which package should it be assigned to?
I will look at the wiki to see what debug info I can attach.
