Now it reports it, or at least something much closer to the reality than before.<o:p> </o:p>The AirPlay protocol doesn't provide a mechanism for getting the exact latency (or if it does, we're not aware of that). PulseAudio makes an educated guess, and a significant part of that guess is a latency constant that is added to each latency report. The default value for that constant is exactly 2 seconds, but that's not optimal for all devices. PulseAudio uses a different constant for some known devices, and we'd like to expand the set of known devices. If you find that audio-video synchronization is bad with your AirPlay device, you can experiment with different latency constants by passing argument "latency_msec=2000" to module-raop-discover in /etc/pulse/default.pa. Change the number 2000 to something that works better. Once you find a better latency value, we'd be happy hear from you so that we can add your device to the list of known devices.<o:p> </o:p>Which makes me think there has been some attempt to make sync possible. Yet it seems pulseaudio is ignoring its own latency reporting! When I press play/pause in my player, the output immediately ceases on the local sync, and I have to wait the 2 seconds for it to propagate to the raop device (as expected). <o:p> </o:p>Is there a way to get what I want? Am I going about it complety wrong?<o:p> </o:p>Marshall Eubanks</div></body></html>
