Hi! It looks like this is actually a feature, rather than a bug. In the Gnome volume controller, in the Switches tab, the "Speakers" checkbox controls whether the internal speakers are being used or not. If you plug something into the front headphone jack, alsa turns that off and turns on the Headphone checkbox automatically. The user can select both at the same time if (s)he wishes. These are all independant of plugging speakers into the back.
I suggest rejecting this bug. -- Powermac G5 plays audio from internal speaker when speakers are connected https://launchpad.net/bugs/34237 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
