A question about the console-kit approach, where the user physically near
the sound hardware is the person that gets to use it...
A favorite trick of mine is to ssh into a machine, and use the sound
hardware there to announce some kind of event. It might be an alarm to wake
up a family member, or

Hi all,
I have a laptop Amilo Si 3655 and Ubuntu 9.10 64
I have 2 mic: internal and external.
Internal mic work successfully.
But external Mic and Line-In work as outputs.
Line-In output surround channel.
Mic output Center and LFE channels.
But sometime I need external Mic and Line-In.

To express in a little different words what Colin alread
The power savings on a laptop will be so close to zero, you couldn't
measure the improvement in battery life. 40 interupts per second
(what raw ALSA does) compared to streaming 22KB per seccond to the
sound card is too small to care. You wont notice any improvement.
