Heya Dan, I've found that there is about a 800ms delay between the output data being written to /dev/dsp and being able to hear the output from the soundcard on FreeBSD. I'm working to a 200ms deadline. What's your write size? At 44100khz*2 channels, a 65k write would take around 800 ms to play.

xes behind it. The issue is that tracerouting from any box other than the FreeBSD box shows latencies of 1000+ms after the FreeBSD router beginning with hop 2 when the upstream pipe is being used while the FreeBSD box shows the latency at 40-50ms which is correct under traffic load. Anyone knows
