Which alsa-driver are you using now? At best, try the latest

ftp://ftp.kernel.org/pub/linux/kernel/people/tiwai/snapshot/alsa-driver-snapshot.tar.gz
or the sound git tree at
git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound-2.6.git

The device is likely not "iec958" but "hdmi".

And alsa-info output? Use model=auto from now on.
The default model (acer) doesn't work obviously for your laptop.
