My second question is about sound over hdmi with an Nvidia GTX460
(NVC4 /GF104 family):

aplay -L gives
hdmi:CARD=NVidia,DEV=0   ->  pcm3p/
hdmi:CARD=NVidia,DEV=1   ->  pcm7p/
hdmi:CARD=NVidia,DEV=2   ->  pcm8p/
hdmi:CARD=NVidia,DEV=3   ->  pcm9p/

but only pcm7p actually does anything.

So currently I use
load-module module-alsa-sink device=hw:1,7
to add a sink, but PA automatically adds pcm3p as "GF104 High
Definition Audio Controller Digital Stereo (HDMI)",
so I effectively have two nvidia-hdmi sinks, one of which does
absolutely nothing.

Is there any way to disable the automatically added sink OR define
which device to chose as default?

What you want to do is add probe_mask to your snd-hda-intel module options. If you google nvidia hdmi probe_mask you can find an explanation.

For example I have in /etc/modprobe.d/snd_hda_intel.conf:

options snd-hda-intel probe_mask=0x102
