Sorry loadman. Didn't mean to imply that my crash is related to the audio setting. I just found it interesting that another crash has the same cascading effect.
I've mentioned the ctrl-alt-del crash before (I believe you said you couldn't reproduce), and it has never been a big enough deal to make a stink about it because it doesn't happen with "normal" usage, and the workaround is to open the Options dialog before hitting ctrl-alt-del. Frankly, I have no idea about the audio setting. If the audio setting is also used to enable video snap audio and/or game selection audio, then it is on. If it is just used for jukebox stuff, then it's probably off. I'd be glad to do more investigation work for you if you'd like, loadman.
Sorry for the semi-unintentional thread hijack!
