Assuming you are already using Gutsy, you could try enabling the backports 
repository, which I think it is labelled Unsupported Updates in Adept, and 
then install linux-backports-modules as this contains version 1.0.15 of the 
ALSA drivers for Gutsy. I installed this just today on my Toshiba laptop to 
fix a couple of issues with my sound using the same snd_hda_intel module (It 
is now much louder and plugging in headphones cuts off the speakers as it 
should do).

Do you also have the following line at the end of 
your /etc/modprobe.d/alsa-base or something similar?

options snd-hda-intel model=asus

You will need to reboot for this change to take effect unless you can unload 
and reload all the sound modules. I have seen the line above fix issues for 
other ASUS owners.

Hope that helps.
