Sound card problem in Acer Aspire 4520

Recently I bought a Acer Aspire 4520 laptop. I installed some Linux OS includes Fedora 7, Open SUSE 10.3, Ubuntu Fiesty and debian. But None of my installed OS detected my sound card. Finally I removed all the distros and installed Ubuntu Gutsy 7.10 and then downloaded latest ALSA-Driver from Installed this driver. Now My sound card is working fine. Here I have noted the steps what I have done for my sound card problem. It will useful for someone to search solution for this problem. And here I have given the link for ubuntu forums. Seems, more people getting this problem. Ref this page, before you start to install the alsa,

Steps for installing the ALSA Driver:
* Installed Ubuntu Gutsy version for 64 bit
* login in console mode
* By default, the nvidia driver installed. Install the driver by using
$apt-get install nivida-glx-new
$sudo nvidia-glx-config enable
Then retsart the Laptop. Now almost the video problem will solved.

* Updated the packages.[kernel also updated]
* Installed build-essential from package manager. It has resolved lot of dep problems.
* Downloaded alsa-driver-1.0.15rc3.tar.bz2
* Untar it
* $./configure
* $make
* $make install
* sudo vim /etc/modprobe.d/alsa-base
added this "options snd-hda-intel model=acer" in almost last line. Aft that save it.
* Reboot
* Now my lapy logged in with nice Ubuntu sound. The sound card working fine.
Thanks to ALSA and Ubuntu....
This is the common steps for all the distros.
Have the Fun..

Me too have an acer aspire 4520 but with RHEL 5. Me too want to install alsa-driver-1.0.15rc3.tar.bz2. In your post, what is snd-hda-intel? Can I add the same line in /etc/modprobe.d/alsa-base through sudo vim?
