I've just tested with 32-bit float and this works perfectly (I can see its 32-bit float in the pulseaudio debug output).
I think pulse can accept up to 32 audio channels, I have added a 7.1 section to the pulse output but I don't have any source material to test it with.

Forcing ss.channels = 8 causes pulse to open up a 7.1 channel stream so I assume it works, 
though I do need someone to test as I only have 5.1 speaker setup anyway.

Attached is an updated patch from the original 0.9.4 source incorporating these two updates.

kind regards,
Danny
