Ed, can you try with master git? i think it's already been resolved in a
different way there. Can't find any reference in git log though.

It would be nice if the PA api didn't actively hate its consumers so much. 
I'll take a look at the patch when I can.

pa_stream_drain_3.patch

Oh, it hates you.

Handle case where pa_context_connect does not immediately succeed.  To be
applied on top of pa_stream_drain_2.patch.

Riccardo - I didn't see anything in git past the fix to bug 13604, which
this
is a continuation to.

The changes were not to the pulseaudio backend but elsewhere. This explain why
master git works fine. At least for me :)
