    No sound in precise after kernel upgrade

    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

    Yep, same here. Ubuntu 12.04 (64-bit) and HP Pavilion DV6. The 3.2.0-24 kernel works fine. Is there a bug filed against this somewhere?

    Re: No sound in precise after kernel upgrade

    DV6 (1375DX) with 3.2.0-25 had two problems.
    I dual boot win7 so I know it's all software, windows works great.

    1. No sound via laptop speakers but front jacks work as usual. I tried everything to fix, kernel downgrade is the only solution I found.

    2. After resuming from standby the unit powers on. You see the background for a instant then ALL power cuts out. The only way to get the unit to power up is to unplug and remove the battery. After this it will work fine until it has to resume again.


    Wow developers, in six years nothing like this has happened. Not one major problem but two totally unrelated issues with one update. I have been using Windows again for the last few days.....

    Hey guys, I found a bug report on launchpad describing the sound issue we are all experiencing:
