CentOS docs - Aug 2008 - Acer laptops (and the snd_hda_intel module

Just a note for anyone doing a page on Acer laptops.  I had put in my
own page, and notice that someone had put in theirs as well, that though
the module loads, sound doesn't work. 

It turns out that one can get sound working by downloading the latest
alsa drivers. I've added a note to my page on the 4720z.  The issue
seems to be that CentOS uses an older version of alsa.

(I also, of course, added the caveat that this means using something
untested by CentOS developers.)
Thanks to Alan for reminding me about this.

Are you sure the provided alsa/snd-hda-intel module doesn't work with 
your hardware ?
I had to specify the model name in the /etc/modprobe.conf (model=imac24 
because i installed on my iMac ;-) )
Maybe adding a link/note on the wiki about all the parameters that this 
module accepts is worth writing : all the paramaters are in the file 
/usr/share/doc/kernel-doc-2.6.18/Documentation/sound/alsa/ALSA-Configuration.txt
(package kernel-doc)
