I had played several times to that point with different characters, to test if it was just a damaged save file. Same error.
It would stop where the person walks up to the shrine/stone. The first time unmuted, after he walked up, there were sparkles, and then he walked back away from the shrine. I aborted, went back to my original character. It didn't work. It still stalled at the same place. I closed out the game, restarted the save file, I got sparkles and it continued on. The un-mute wasn't 100%, but it worked on both saves. (I removed the mute before starting the software.) Maybe it was only a workaround for OSX, I don't know. Good luck!
