Comment 4 for bug 497221

   After a lot of trials I have somewhat solved the sound problem although not perfect.

   This is exactly what I did so far.

   I made a full installation (dual booting with windows 7) with dedicated ext4, swap partitions. No sound yet.

   I removed alsa using synaptic package manager.

   I added keramic backport to the sources & updated.

   I installed 'linux-backports-modules-alsa-2.6.31-17-generic' using synaptic package manager.

   Restated the system & after some tweaking in the sound settings I got sound ! Mike is working fine too.

   There are still issues with the sound like the laptop speaksers remain on when I connect the headphones.

   I'm managing right now using the gnome alsa mixer to manually reduce the laptop speaker sound while using headphones.

   I hope this bug will get fixed for the next release of Ubuntu. As of now, I'm able to use my new laptop with Ubuntu 9.10
