Yeah this is definitely sensible. I'm hoping the Skype guys will remove
the whole dropdown selectors when PA is detected to avoid people
expecting that alsa and pulse can play nicely together in a system
without one or other ultimately being locked out at some point.

Hmm, it's strange that this is somehow different on PA vs. Non-PA....
the code for echo cancellation should be the same regardless.

There were some skype related fixes in the stable-queue branch recently.
I believe all these fixes are in the PPA you mention for Ubuntu. I don't
think these are related but there are lots of misc bugfixes between
0.9.19 and 0.9.21+stable-queue anyway, so it's always best to use that
Let us know how you get one with that one.
