Comment 2 for bug 297864

Hi this is the first time I use launchpad, I hope I use it correctly if not I apologize.

I have the same problem.
I have ubuntu 8.10 (intrepid)
kernel linux 2.6.27-9 generic
Gnome 2.24.1
on a
ASUS U1 ultra SLIM

When I plug in my headphones, the speakers don't go off

it is a real problem for me as I need to talk over skype and the whole family must hear to my conversations. What can I do?
p.s.
I attach buginfo. txt I obtain with
(echo '== Sound cards ==' && cat /proc/asound/cards && \
echo && echo '== aplay -l ==' && aplay -l && echo \
&& echo '== lspci =='&& lspci) > ~/buginfo.txt
