I report this bug just for information, cause it took me several hours to find out the solution.

--- System ---

Description: Ubuntu 10.04.1 LTS
Release: 10.04
Package: alsa-base 1.0.22.1+dfsg-0ubuntu3

--- Problem ---

After installing Ubuntu 10.04 LTS on HP 625 Notebook, you won't get sound through the internal notebook speaker. Line-out works perfectly.

The ALSA Information Script reports the wrong hardware:
HDA-Intel - HDA ATI SB
IDT ID 7667

That's because of the wrong alsa driver version, missing the newest drivers:
Driver version: 1.0.21

--- Solution ---

You need alsa driver version 1.0.23 or higher. To install at least driver version 1.0.23 at this time, take the following steps:
* Activate the "Unsupported updates (lucid backports)" repository in Synaptic Package Manager (Settings -> Repositories -> Updates).
* Reload your package information.
* Install the package "linux-backports-modules-alsa-lucid-generic". This will also install a new linux kernel version.
* Restart and your sound should work properly.
* If not, raise all available volume levels in alsamixer (start alsamixer in terminal).

Now the ALSA Information Script reports the right hardware:
HDA-Intel - HDA ATI SB
IDT 92HD88B1
