Public bug reported:

Binary package hint: pulseaudio

Hello, 
everytime I watch a music video in totem (or with whatever application) I have 
the problem that the music is not in sync with the video.  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.
Thanks :)
