I usually agree with the 'stick to latest versions' thing, but I believe one thing should be noted here:
http://www.alsa-project.org/main/index.php/Main_Page_News
The official ALSA releases have been kind of rare lately (1 during 2010, and the latest being 2011-01-31), so the only way to keep it updated is to actually compile it, which can be a problem for those users who don't have a clue on how to do it; just think at those who try Linux (mostly Ubuntu) and then find out their games/programs aren't working as they expected under Wine (and believe me, I've seen way too many of those)...
I don't want to sound harsh, but unless there's a better way to keep alsa-plugins updated (at least to a version that does make the sound work), PA shouldn't be considered 'supported through alsa'
