paex_sine choppy on Raspberry Pi, defaultLowOutputLatency too low
I compiled and tested paex_sine on the RaspBerry Pi 2 model B.
The sound was choppy, as if it was constantly underflowing. This was not an occasional glitch. It was a steady buzz.
As an experiment I changed the suggestedLatency from LowOutputLatency to HighOutputLatency. Then the output became smooth.
According to pa_devs, the defaultLowLatency is 5.8 msec. I found that I needed to use a latency of about 30 msec to get smooth sound.
This is a small part of a larger meta bug #97
