As most of you know, there's an audio sync issue when streaming video
through RDP. The audio is delayed by about 1 second. I've been doing
some research for a low latency audio server as opposed to using OSS and
saw a project called JACK (http://jackit.sourceforge.net) which looked
promising. Has anyone else had a requirement for streaming media
through a remote display protocol (either RDP or their own proprietary
protocol) and run into the same issue of audio/video syncronization?
I think it would be interesting to see JACK as part of rdesktop as an
available audio server because then we would see close to perfect audio

The problem is not that oss has too much latency. The main problem is
the currently completely missing audio-sync from the windows terminal-
server. I just found a way to sync the audio to the display, but this
needs a major rewrite of the sound-drivers (RDPSND_UNKNOWN6 is in fact
a sync-packet from the ts).
This will have to wait after the 1.4.1 release. I plan to integrate
samplerate conversion then, too. This will add support for onboard-
soundcards only working at 48kHz.
