Well, I am having the same problems he is, as is my dad and sister (they use the same computer). I can handle going and fixing it every time I want to listen to something, or watch a flash video. My dad is starting to become very annoyed with having to switch between ALSA and Pulse Audio so that he can use Skype, then listen to his music, then watch a video on MSN. I am pretty sure all the sound problems have turned my sister completely off on Ubuntu, to the point to where she may never come back.
My dad used to even brag to people about how he doesn't have to deal with all the crap on Windows, but is still just as productive. Now, when he talks about it, there is obvious agitation and reluctance in his voice. All because of this Pulse Audio crap. My sister will call me up asking to fix the sound. My dad will call me up asking to fix the sound. Before Hardy, they _never_ had a problem with anything sound related. They hardly had any problems at all.
Now, don't get me wrong, I think the ideas behind Pulse Audio are great. But I also think that they currently are not implemented well enough, especially for an LTS release. In my book, that just isn't acceptable. It could have waited 6 more months. It should have waited 6 more months (at least).
