Comment 23 for bug 438318

@PeteG

Thanks for the new things to try!

I updated to the latest pushed karmic kernel. I enabled karmic backports and installed the alsa modules. I rebooted.

No joy. Headset jack audio is great (very loud and clear in fact) but nothing from the main speakers. External speaker sound worked on Manoj's kernel patch (alsa quirk) before applying the upstream alsa patch for the hp mini sound. When Tim sucked in upstream's changes it stopped working.
