PulseAudio definitely allows the playback application to query latency (see pa_stream_get_latency() and pa_stream_get_time()), and AFAIK, it has always done so.

There is no "big" latency, but still too much to watch the video without noticing the latency. If you see a drummer you see the stick touch the drum and after that you hear it. With pulseaudio and other abstactions the problem becomes bigger and bigger. If I always I think we need some kind of infrastructure that lets the playback application (e.g. totem) ask the "last" abstraction layer (e.g. pulseaudio) how long the audio latency is. Then Totem for example has to delay the video exactly that long, that both are in sync. If I as a musician watch music videos I go bad, because this latency is not normal/natural. I know that this is "Wishlist" and that many applications are affected, but I think this is a necessary step one have to take. It's really annoying. I also know that there are realtime kernels and other sound servers like jack, but I think it's also important that pulseaudio etc. don't act on the cost of synchron audio/video.
