Comment 36 for bug 108392

I found a very strange thing about this.
My laptop is HP/Compaq V3182. During the first 10 days, I cannot heard any sound in Ubuntu, but from one day on (I can't remember the date), the sound comes out.
And not until the feeling of exciting gone, 3 days later, someday evening, when I open my laptop and enter Ubuntu as usual, I lost my sound again.
These days, things changed again, when I use a headphone, I can hear the sound, but I cannot heard that without headphone.
Aha, I saw that this issue happens not only on my HP V3000 series laptop.
