I know you've said that the package is using 1.0.17 but there is a 
chacne that the Ubuntu package updated the pulse plugin to the latest 
version in git (from the 1.0.18rc3 tree).

If this is the case, then Takashi found a problem with recording via 
alsa with these recently on the alsa Mailing list.

Lennart has yet to ACK this and an earlier message on the Alsa mailing 
list from a couple weeks back (unless he's done so privately to Takashi) 
so I'm guessing he's a little behind on things right now.

In lieu of an ACK from Lennart, it may be worth trying out the patch 
from Takashi.


I'd also like to know if it works (not had a moment to try yet) so I can 
issue an update package for this.
