I came here hoping to find others that may have solved this issue (black screen then bout.exe has stopped working crash) but it looks like nobody had and the sound changes are not working for anyone.
I checked out the ogre log and noticed that everything works fine, even the openAL driver is starting up fine and then it stops dead after:
21:00:12: AL Source test successfully found 32 possible sources
21:00:13: Load savegames
To test if its saved game corruption I was thinking, I went into the savegames folder and moved all the saves completely out and to a backup folder. Now with the folder completely empy I started up the game and it launched perfectly, absolutely no crashing what so ever now. I'd check out the saved games on a system that does crash, like mine (I can upload them if you want) and see what is causing the problem and work with a backing up system in a future patch, if this is the case.
Hope that helps some other peoples issues.
Upon looking at the saved files, my _autosave.ksg was well under half the size of my previously last saved game so that had to be the culprit. Moving back all my saves but for the autosave file and I'm back in action to where I last left the game.
