I did a quick Google search and it appears your EEE is significantly different hardware-wise than my 900ha. I think maybe yours has Nvidia graphics and audio; does that sound accurate? You can confirm this with the terminal command:
I am not an expert on Nvidia but I know Debian does not include these "non free" drivers by default. Hopefully one of our resident Nvidia-in-Debian experts will be along shortly to assist. You can read about Nvidia on the Debian wiki (but proceed with caution; perhaps better to wait for some guided assistance than to forge ahead):
Apologies if my Nvidia guess is inaccurate.
