I am unable to change my sound device from within the Second Life preferences, no matter which one I select even after a relog, it still stays with my Windows default device. I am able to change my Windows default device to do what I need to do but would prefer to use the feature that is in Second Life if it worked. I know this is not just my PC that is failing to be able to do this because I only noticed this when I was trying to help a friend with their sound and theirs did exactly the same as mine.
