Hi.

It'll probably be helpful to add AL_PRINT statements in pulse_open_capture to 
print out the parameters, in pulse_available_samples print out the number of 
samples being reported, and pulse_start_capture, pulse_stop_capture, and 
pulse_capture_samples to see if they're ever called. Then you can filter the 
output on lines that have "AL lib" to see what's going on.

The capture sample program in Creative's SDK seems to work using PulseAudio 
0.9.21 for me, so the only thing I can think of that may be wrong is it's 
using values that don't work well with Pulse (and yes, Pulse's capture code 
was changed recently, to allow reading directly from Pulse's buffers as much 
as possible for fewer intermediary steps).
