Singular issue? I had multiple issues. It resolved the issue of the
volume hotkeys not adjusting the headphone volume. 

I had another issue where the "VolUp" button was not changing the
volume. I have now tracked this one down to the gconf key 
/apps/gnome_settings_daemon/volume_step which I had set to three (3). If
I set this to 4 or more (or zero so the default of 6 is used), the VolUp
button now works, but each volume down step is different from each
volume up step. It looks like a rounding issue, and when the step was 3,
it was not enough to round up to the next increment. Should I file a bug
against gnome-settings-daemon for this?
