HDA intel does not support hardware mixing, so your distro must be
using PulseAudio or dmix on the default device.

This .asoundrc doesn't do anything, as apps will use the "default"
device, not "hda-intel".
Software mixing *requires* resampling all streams to a common sample
rate, 48Khz by default because not all sound cards support 44.1Khz.
You could configure pulseaudio/dmix/whatever to resample everything to
44.1Khz, but then 48Khz streams will be downsampled.

You need to configure your sound server to output to the iec958
device, as the hardware only supports one stereo stream.

iec958 only supports 2 channels. Either you set up xine to decode
those and downmix them to stereo, or you send the raw AC3/DTS stream
to the device and have your receiver decode it.

Depends on how your distro sets up the default ALSA device, sorry I
can't help more. Does Debian testing use pulseaudio?
