No sound in precise after kernel upgrade

[ShadowMage]

Hi all,

In Ubuntu 12.04, after performing an upgrade that included a kernel update, I no longer have any sound. The sound worked fine before the upgrade. Oddly enough, if I plug in headphones I do get sound through the headphones, but without them I am no longer able to get any sound from my laptop's internal speakers.

I'm not quite sure what additional info I should provide, so here's some info to start. Please let me know if there is anything else I should add.

Laptop: HP Pavilion DV6
OS: Ubuntu 12.04 (Precise Pangolin) 64-bit

$ lspci | grep Audio
00:1b.0 Audio device: Intel Corporation 82801I (ICH9 Family) HD Audio Controller (rev 03)

$ uname -r
3.2.0-25-generic

Many thanks in advance for any help!

Same problem.

Change kernel to 3.2.0-24. Works for me.

Same problem for me. This morning I upgrade from 3.2.0-25-generic-pae to 3.2.0-26 generic-pae, but nothing changed. Linux kernel 3.2.0-24-generic-pae works fine.

Is it not possible to see the difference between two kernel in any way?

Thanks

I found that updating my kernel to 3.3.4 solved this problem for me. My system is 64bit (HP DV7-2180us) and these were the directions.

cd /tmp && wget -O linux-headers-3.3.4_all.deb http://goo.gl/TchWu


sudo dpkg -i linux-headers-3.3.4_all.deb


cd /tmp && wget -O linux-headers-3.3.4-generic_amd64.deb http://goo.gl/qJcW4


sudo dpkg -i linux-headers-3.3.4-generic_amd64.deb


cd /tmp && wget -O linux-image-3.3.4-generic_amd64.deb http://goo.gl/arQWv


sudo dpkg -i linux-image-3.3.4-generic_amd64.deb
