I also have that and sound works fine here. So, I would say not a
problem.

You must have run alsainfo.sh after you corrected your system because
this is not what it showed. It showed that the default was pcm
(analog). For some reason, at start up, your system is defaulting to
the iec958 (digital) interface on your nvidia card at startup.
Not the nvidia card: I recently installed this card and the problem
existed before.
What
happens if immediately after startup you run?
aplay -D plughw:0,0 [some wav file here]
It has to be a wav file as there is no decoding in aplay. You should
get sound without making any changes to configuration.
Yes, that works

This is correct, but the erasure, I don't know where that is coming
from.

I suspect, because of the signature at the front, that those files are
recreated by pulse at each start. I think *you* have to create the
configuration files in your ~/.config/pulse directory.
Try this:
cp the /etc/pulse/client.conf file to ~/.config/pulse.
Edit the home directory file and change the line
; default-sink =
to
default-sink = hw:0,0
This does not work.
That should do the right thing at next boot.
If it doesn't work, run
pulseaudio --dump-conf
