In anyway, if this is reproducible, get alsa-info.sh output before and after suspend. It'll give more information of HD-audio and sound driver status.
No significant difference before and after the suspend
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?
Attaching the files.

Bisected it to commit 3f50ac6a0e "ALSA: hda - Fix stream and channel-ids codec-bus wide"
Reverting this on latest git fixes the sound.
Could you get alsa-info.sh output before and after reverting this, too? (i.e. non-working and working states)
Hmm, now there's no sound even with the revert. I guess reproducing this is not completely reliable so the bisect gave a false result. Oh well.
Thanks, Miklos
