libao pulse driver fault
Hello. I have some problems with using pulse driver for libao.I launched "pacat --record | sox -t raw -r 44100 -s -b 16 -c 2 - -t ao pulse pitch -500" for processing audio input, but it faulted with "Assertion 'p' failed at pulse/simple.c:384, function pa_simple_drain(). Aborting". Using other drivers, such as alsa, works fine, but I need pulseaudio. So is it because of libao and how can I solve this problem?
Ubuntu 10.10, PulseAudio. libao 1.0.
