On this page I have founded following answer:

Code:

 Re: [SOLVED] Sound problems-Intel 8201I (ICH9 Family) HD Audio
Alright folks, good news! The audio situation is solved for anyone using the IDT 92HD71B7X audio codec. Comes in most HP dv4, dv5, and dv7 laptops. The solution as found here:
https://bugs.launchpad.net/ubuntu/+bug/269586

The solution is quite simply.
First:
Code:

gksu gedit /etc/modprobe.d/alsa-base

Then add the following to the end of the file:
Code:

options snd-hda-intel enable_msi=1

For me this worked on a clean install of Intrepid. Also, make sure you remove any kernel options you put in place to get sound working previously, such as noacpi, pci=noacpi, or irqpoll.
Since two of those reduce you down to one core, and the last one screws around with trackpad response.

The above mentioned solution seems to fix all my flaws, and now I seem to have everything I need working on my dv4.

Hope this helped most people.
