I haven't really banged on my system since I applied the patch, so I'm not sure whether my system is behaving any differently than yours. I think I had a hard freeze when using asamixer, but I routinely use envy24control and I have not had a problem with that. I'm in the middle of a pile of other work, but I would be interested in what ever you find and I should be able to help with some testing in the not too distant future.
