one of my friend told me about some 'backport package' in ubuntu could any one confirm it?
i am in need of confirmation. i cannot format system again again...........

i still need an answer

In linux word I don't have a lot experience, but I did some search and found how to make sound work with this sound card.
I have hp pavilion dv5-1010en with Ubuntu 8.10 32bit, kernel: 2.6.27-9-generic.

Firstly I "Update to the Latest Version of ALSA"
https://help.ubuntu.com/community/HdaIntelSoundHowto#Update%20to%20the%20Latest%20Version%20of%20ALSA

Then: "Manually Specify Module Parameters" of my sound card. Everything is here:
https://help.ubuntu.com/community/HdaIntelSoundHowto#Manually%20Specify%20Module%20Parameters
I found somewhere that model=hp-m4 works, so I used it.
I add in /etc/modprobe.d/alsa-base this line: options snd_hda_intel model=hp-m4 enable_msi=1. Without enable_msi=1 I think it will work too.

And in the end I found that this can help to enable sound. So I add it to /etc/modules:
http://ubuntuforums.org/showthread.php?t=570442#3

Now I have sound, but have problems with headphone output. It don't work. ;/ If you need some additional information be free to ask.

Some info:

With new kernel 2.6.27-11-generic everything works fine.

I find that if headphone jack is inserted speakers stop and Headphones work fine, however the 'Headphone as line out' switch is no longer available.

In Kernel 2.6.27-7-generic this allowed sound through speakers and jack with different volume setting using the 'headphone' and 'front' sliders which was quite nice. This version did not however work with the 2nd output jack using the 'surround' slider.

This all worked fine in Hardy, what happened??? :-(

Were you able to solve your problem??
I am having the same laptop and the same problem, I have been working for 2 days continously trying everything I find on the internet...but still there is no sound at all.

Hi.

The solution I posted in my blog: http://zdes.wordpress.com/2009/04/16/solucionado-sin-sonido-en-jaunty-jackalope/ - in Spanish - but even so you can translate with google.

Turning off the computer generates an interruption - a crack - but the sound is generally very good

This solution is also for Hardy - update -, Ibex and Jaunty.

Bye and greetings from somewhere in Colombia!!!

Is there any chance you could send me you solution from your blog. I am in China and many wordpress blogs are blocked and I cannot see.

I have a Compaq CQ-61 and have tried nearly every possible solution posted with little success. I can definitely see my sound card working (through PulseAudio) but I get no sound from speakers or headphones...nothing.

Thanks in advance for your help.

Thanks argordmel, that solved my question.
