Hi Daniel,
installed linux-backports-modules-alsa-karmic-generic and rebooted the system but still sound comes from headphones and speakers simulataneously...

sound information generated from one of the troubshoot guide
http://www.alsa-project.org/db/?f=19ba14f69566e519befb756ebbde7852c877302f

amit@amit-laptop:~$ head -n 1 /proc/asound/card0/codec*
Codec: Conexant ID 5067

amit@amit-laptop:~$ aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: Intel [HDA Intel], device 0: HDA Generic [HDA Generic]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

i think my sound driver is not being used by the alsa as it is showing it using GENERIC driver.
and the driver Conexant is not even supported by ALSA

so how can i go about this ??
do i need to live with this problem or there is any hope..

thanks much
