Yes, the correct sink module is module-alsa-sink. There is no need to 
load it explicitly, though, as module-udev-detect already loads it 

PulseAudio does not use the passthrough mode by default, because it has 
no idea that the receiver supports it. So you have to configure this 
explicitly. I recommend using pavucontrol for this. It is as easy as 
selecting a digital stereo profile and checking some checkboxes that 
correspond to what compressed formats your receiver can accept. On exit, 
PulseAudio will save their state, and restore this information on startup.
