The hw output looks healthy in both cases. I have similar output on my
lenovo laptop. You could do an `alsactl init` after suspend and check
afterwards what sound card is used as default in `alsamixer` or
`cat /proc/asound/cards`.
Sound issues are a bit weird. Last time I had no sound (on Stretch) I
went through the steps above and everything looked healthy. So latest
alsa drivers fixed it.
Hope this helps.
