For some reason i got a quest to go to a cave, went to it found the wall and it plays the sound sbut does not absorb. I tried to reload a previous save where I was by another wall and had it also had broken despite workign minutes prior. Any ideas what may cause this or how to fix it as it stops a quest.

Good question, I had it happen to me on word wall. Only advice I have is to keep reverting save, maybe even go back a bit farther. If you're on PC there is probably a console command to get the shout. Also as for the first one you got, check the shouts to see if it already took and you're trying to get it again. Sorry I can't help much.
