No sound in HP Pavilion dv6z laptop with ubuntu 9.10

[leandersp]

   I purchased a new HP Pavilion dv6z laptop & tried to boot ubunutu 9.10 using live cd as well as external hard disk. No sound at all.

  I went to the sound settings by right clicking on the volume icon & tried all the options - no luck. Please help. This is what is holding me from a full ubuntu 9.10 installation in my new laptop.

Regards

   Thank you for the response.

   Yes, I've tried that. No sound. If there are any other methods available
to get the sound working, I'm willing to try them when I have time. I tried
googling but did not get a working solution for this problem.

Regards
Leander

   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

Tried Ubuntu 10.04 beta 4 in the same laptop. No sound. Should I flag it as a new bug ?
