This audio delay will happen on any RDP client without special multi-media redirection. The extra hop the sound has to make in your architecture is probably making the delay more noticeable.

The release in beta has support for VC-1 and mpeg h.264 direct decode, but that doesn't sound like it would help with this application.

Since it's a terminal emulation package, have you considered trying the application under Solaris as a lot of work had been done in the recent past to remove as much latency as possible for softphones under Solaris.

Hi
We have a fully patched sun ray server running uttsc to a windows 2003 terminal server. The users are using a terminal emulation program to access a character based ERP system.
All the sound through the rdp connection is delayed or lags about 4 seconds.

I found on google searches that this was a problem back in 2006 and Sun were working
on fixing it.

Does anyone have any updates or a way to fix this?

It makes the Sun Ray nearly unusable because the users rely on a beep sound to alert them when scanning in stock to a warehouse. Without the beep they make mistakes which
costs the company money.

Thanks
Michael.
