Audio works!
Updated the static page.
Basically, you need to pass the parameter “model=toshiba” to snd-hda-intel after you download Realtek’s drivers (which are pretty much a wrapper around the official ALSA tarballs) from http://www.realtek.com.tw/downloads/.
Happy time is now!

I made an attempt to just use the latest ALSA driver, utils, and lib packages on a similarily configured laptop, a Gateway T-1616. For Debian, this method required, of course, the kernel source and also the ncurses-dev, build-essential, and gettext packages. After untarring the alsa-driver-xxx.tar.gz at /usr/src/alsa, I just passed
#./configure –with-cards=hda-intel && make && make install
and
#./configure && make && make install
for the lib and utils packages.
