The important thing is to get the alsa-info output at the moment
you don't get sound and you get sound.  Just after the suspend is
still in the power-saving mode, thus all the setup might be inactive.

Anyway, could you attach alsa-info.sh output so that I can analyze?

Could you get alsa-info.sh output before and after reverting this, too?
(i.e. non-working and working states)
