Tanu Kaskinen had a look at the files.

Don't have pulseaudio installed but please try something.  I am on debian.

Duplicate /usr/share/alsa/alsa.conf and from the duplicate remove alsa.conf.d
import reference.

I am fairly sure this will cause normal alsa to fire up without pulse as
default.

I might have thought of another way to skin the cat.  Can we make pulse alsa
pcm completely fail when suspended.  So that while suspended alsa spins threw
its detection its the pulse alsa pcm and it simply fails like if pulseaudio is
not running at all when suspended.  This might be enough to send alsa back to
setting itself with default working again.

The issue might be that pulse pcm interface is not failing bad enough so alsa
ends up in a bad state because it thinks the pulse pcm is a working interface
when its not.

In one way you could say that pulseaudio is perfectly emulating broken sound
card in its current suspended mode.  The look of default pointing to something
that does not work is exactly what you expect a broken sound card that will not
put out on alsa todo.  Basically get the pcm plugin to follow the code path it
does when it does not detect pulseaudio.

That might magically get to the state that suspended is exactly like pulseaudio
is not running.  It all could be a minor case of pulseaudio not emulating a
sound card well enough.
