I have run into what is basically another instance of bug 3470
(pulse_hw_params asserting because the stream is already initialized).
The application that I am working with is calling snd_pcm_hw_params each
time it plays a sample. The following patch makes things work for me
(actually the app still doesn't work because it uses poll() in a way that
is incompatible with the pulse plugin, but that is a separate issue, and I
don't know if it should be considered a bug in the plugin.)

I couldn't add this to the bug because it was marked as resolved.
Any comments? Or is the app behaving in a way that is counter to the
Also, I'm still encountering bug 2601 (a separate assert failure that
happens if period_size == 0) even with the patch to pcm_ioplug.c. I think
that PERIOD_TIME and PERIODS need to be constrained; I added a couple of
comments to the bug.
