currently, the test is not self-checking, i.e. the results are not 
compared against known-good values

basically the test just checks if the codes crashes or not; and one could 
manually check the values -- there is room for improvement

for a stronger proposal I suggest to illustrate a convincing/meaningful 
scenario? what does PA_RESAMPLER_VARIABLE_RATE do? how are algorithms 
selected currently?
