A bug was reported in Ubuntu a while ago about Asus Z37E not having audible sound after resuming from suspend/hibernate[1]. A git changeset signed off by Daniel T. Chen and myself [2] was accepted and is in the last 2 Ubuntu releases along with the development one.
I filed a bug [3] in ALSA with a patch attached, then realized that the surrounding lines wouldn't match up in trunk so updated the patch and put it in the bugtracker and tried to email it here. The email didn't pass moderation, but now I'm trying again as a subscriber.
It's just an addition to the quirks table for patch_realtek.c to set 2043:8284 to use 6stack-dig.
I'm trying to get this accepted here so that Ubuntu's not the only distro where sound works consistently across suspend/resume cycles.
