It's not a "problem", it's inherit to RDP.
Think of it this way:
Source ------> MS Server (decompress, decode, transcode) ====> Client
(note the fatter pipe)
Add another hop for Sun Ray
Source ----> MS Server (decompress, decode, transcode) ====> Sun Ray
Server (transcode to SRSS) ====> Sun Ray

We are seeing about a 4-second delay in audio output on Sun Ray DTUs
coming from any Windows system via RDP.
We've tried with both the current version of the Connector and
rdesktop, both have the exact same symptoms so it appears to be an
SRSS problem, not a Connector problem.
Playing any video (no matter how small), whether it's mpeg, flash
based, etc. - the audio starts 4 seconds after the video, and stops 4
seconds after the video - even if the application is closed... it
keeps playing for 4 seconds.
We see this with zero load on the servers, only one person using one DTU.
I'm told that even playing an audio file has the same effect... the
scrollbar slides for a while before the audio starts.
It appears the Sun Ray Server software is performing way too much
buffering of the audio.
Has anyone else had this experience?
FYI:
SRSS 3.1 + 120879-05
T1000 running Solaris 10 1/06
For what it's worth, I've seen this work several years ago when I set
up a classroom for a local charter school... 30 users on a V210 with
no sync problems using rdesktop ( 1.2 I think).
Thanks,
Kevin
