Terminal services and delay in sound redirection

Hi there,

I have a DSS player running on terminal server (W2K3). This program play’s
recorded sound files. Sound redirection works good only there is a delay. You
notice this delay the moment you press the stop button in the DSS player. The
sound file continues for two seconds.
I’ve been testing with DSS, WAV and MP3’s. All these extensions have the
same symptoms.

Possible causes (in my analysis, let me know if there are more):
1. the DSS player
2. rdp audio driver
3. audio redirection from TS to Client

Actions taken:
- used different file extensions
- used different programs: windows media player has the same delay (this
exclude cause 1)
- when I use the DSS player on a local workstation there is no delay
- tested with different clients. WinXPpro laptop and Linux thin client
(Igel). Both clients have the same delay.

Is there anyone with experience in audio redirection on a terminal server
who can help me?

Idea’s:
- Maybe there is a setting to change the buffer size of the audio redirection?
- Is there a possibility to install a different RDP Audio Driver?

My target: remove the delay of two seconds

Sincerely,
Yuri
 
Re: Terminal services and delay in sound redirection

I don't think that there's much you can do about this.
Audio quality in rdp is not configurable, and not very good.
Audio quality in Citrix is configurable in 3 levels, with different
bandwidth usage, and the quality is much better.

But despite the quality in Citrix being better, I have recorded the
same delay as you mention.
