Since Jacob didn't mention it, let me say that this totally unbreaks audio on my Dell laptop (Studio 1558). It is impossible to record audio without this patch; works fine with it. It would be great to get this in before the tree locks, so please test this if you have an Azalia, especially one of the two codecs mentioned, and report results to Jacob. (Mine is: azalia1: codecs: IDT 92HD73C1) Thanks
