[pulseaudio-discuss] module combine not respecting requested latencies

Hi all,

I was toying around with the combine module, but it appears it adds a 
lot latency for no good reason, changing it from 200 ms to 10 ms makes 
some applications like wine happier. I wanted to see if I could fix it 
myself, but I must admit I don't understand what the various parts of 
that code do. The fact that is's both an input and output make it even 
A naive patch to fix it is here, but it would have been nice if module 
combine would just respect the latency I ask it to set, and maybe just 
set a high latency by default otherwise.
