Problems with bsnes and libao's pulseaudio driver

Hi, I am not sure what to do with this one. As you might know, I packaged bsnes which is currently sitting and waiting for review. Now, I found and issue with bsnes and libao's pulse driver, which is the default one as of 0.8.8, which is going to hit Fedora 8 soon. The problem is that bsnes works perfectly fine with alsa and oss drivers, but pulse makes the PA daemon go sky high in the cpu usage, and exit after a few seconds exhausting its cpu time limit. byuu, bsnes author, says that libao utilisation is very simple and should not do anything bad. On the other hand, ogg123 works fine with pulseaudio. Any suggestions how to proceed? Regards, Julian
