Hi, I'm using the Pulse Audio v0.9.21 with Moblin 2.1 OS on an embedded system. I've observed that when a audio stream is in progress through Pulse Audio and a system alert is generated through libcanberra-gtk-play, the system alert is mixed successfully for the first time, but in the second iteration, Pulse Audio either crashes or goes into continuous underruns. Similar issue is observed, when system alerts are generated continuously using libcanberra. As I understand, the underruns could be occuring because of latency added by software mixing in Pulse Audio. Is this a possibility? Has this behaviour been observed on any other platform? Are there any known issues with playback of short streams like alerts through Pulse Audio? Regards Lakshmi
