Then keeping that port makes more sense IMHO, compared to adding an "available" property to profiles. > I'm not sure what you are proposing with regards to selecting ports.

E g in gnome-volume-control, you would still have an output and an input tab (but the hardware tab could be removed). On the output tab you would have: 1) a list of all ports with available != no (assuming we don't optimise ports away) 2) a list of profiles available for that port (stereo, 5.1, etc) 3) balance controls for that profile 4) a "test speakers" button (moved from hardware tab) 5) a checkbox "select this port automatically when it becomes available" Does that make sense? -- David Henningsson, Canonical Ltd. http://launchpad.net/~diwic
