Sound delay wit windows connector and MS Terminal Services

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.

Re: Sound delay wit windows connector and MS Terminal Services

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.

RE: Sound delay wit windows connector and MS TerminalServices

This was one of the big problems I always had with sunray & it obviously
hasn't been resolved yet. 
Using the windows rdp client on a conventional thin client it was pretty
good, yet through the sr2 a 4 second delay.
As far as I can see this problem is unique to sunray. Shame sun seem
unable to do anything about it :( 
I guess it is a limitation of the device & the way the windows connector
works.

it depends also on what you entered when you configured the srss (utadm 
-a). Look at
     first unit address: 192.168.128.16
     last unit address:  192.168.128.240

i'm using realplayer "out of the box". Nothing to configure, or to tune, 
the sound is ok.

i'm too using srss at home, with one dtu!

SRSS 41. beta firmware breaks some SunRay 1g devices?


I just observed that some of our SunRay1g stopped working after 
loading the firmware that comes with SRSS 41 beta. They no
longer produce a video signal (at least no digital one). 
After power-an, the screen with the Sun logo flashes shortly
and then the TFT displays report "no video signal'. 

Is this a known bug?

Matthais, it seems unlikely that you would need to use a new smart card.

Have you tried simply terminating the original session (either 
Ctrl-Alt-Bksp-Bksp or else utsession -k from another login) and creating

a new one with the same smart card?  Of course that's not a solution, 
but it would help isolate the problem.

What OS are you using?  Is it relatively up-to-date with patches?  If 
Linux, are you using the version of Java supplied with SRSS in the 
Supplemental area?  It sounds like a problem either in the OS itself or 
utauthd/java.  Is only one session affected, or are all sessions on that

server affected at the same time?

-Bob

Hi Bob.

We are using SRSS4.0-48 on CentOS4. The CentOS is up2date with patches.
Only the SRSS is missing the latest Patch.

Only a few sessions are affected, but not all on that server. The OSD
shows a 26D error. Creating a new session would help for some days. 

utauthd is using java in  /etc/opt/SUNWut/jre/bin/java, which is version
1.5.0_11-b03

Thanks for your help

Re: Sound delay wit windows connector and MS TerminalServices

FWIW I just tested from both Solaris and Windows.  Both were instant 
sound as soon as I hit enter or released the mouse.

`cat ding.au > $AUDIODEV` resulted in instantaneous sound coming out the 
speakers.

Control Panel, Sounds, playing any of the systems sounds were 
instantaneous once the mouse was clicked.

Michael, Can you test the above scenarios and also let us know what 
versions of SRSS and uttsc you are running (fully patched doesn't tell 
us much) as well as the OS that is running SRSS.

What is the emulation package?  To what type of system and where is that 
system located relative to the Terminal servers?

Mark, I believe what you are refering to is audio and video being out of 
sync.  We have addressed the former with the beta that is currently in 
beta by doing a direct decode of H.264 and VC-1 content.

Re: Sound delay wit windows connector and MS TerminalServices

In the control panel on Windows playing the sounds results in the delay.
Solaris has no delay.

Running solaris 10 x86 05/08 with latest patches
Running Sun Ray 4.1 and uttsc 2.0 with patches .

Not able to run the beta on this set up.

Cheers
Michael.

Re: Sound delay wit windows connector and MS TerminalServices

I wasn't suggesting you try the beta, just that we've focused on 
eliminating the delay that one sees when trying to watch videos.

I've tested this with XP and W2003, with SRWC and with Rdesktop and am 
not experiencing any kind of delay for simple system sounds.

Is the Terminal Server local to the Sun Ray Server?  How many sessions 
are on the Terminal Server?  It could very well be a scaling issue as 
well as I'm testing with one user attached.
