ThinOS 8.0 + T10 + XenDesktop 5.6 = Audio stuttering when playing video.

ThinOS 8.0 + T10 + XenDesktop 5.6 = Audio stuttering when playing video.

Upgraded my desk T10 from 7.1.207 to this drop build. Everything is working good so far except for audio stuttering (and slower video playback). The Citrix VDA on the VM is the latest 5.6.200 version.

Need to try next week against a Citrix Excalibur VM.

RE: ThinOS 8.0 + T10 + XenDesktop 5.6 = Audio stuttering when playing video.

Thank you DContis, we are currently investigating this. Could you help with the below details for our recreation efforts?
-Can you help to explain the type of video that you are testing with? (size, type, bitrate, local/streamed, etc.)
-Do you have any XD policies in place? (i.e. capping frame rate, bandwitdth size, etc).
-Confirm this is a LAN environment with quality network.

Thanks
John

RE: ThinOS 8.0 + T10 + XenDesktop 5.6 = Audio stuttering when playing video.

John,

I tried to watch one of the CNN video today (CNN web site -> video section) and from youtube (default size, quality). My T10 is connected via 100FX I believe but all the server environment (Dell R720 / R610) in on dual 10GB. The audio issue did not exist with 7.1.207. It was never perfect but the audio played fine.

I will follow-up on Monday and post some output from HDX Monitor running from the VM.

FYI this is the T10 I am using everyday (eat your own dogfood approach) to access my Virtual desktop.

We do not have any special Citrix policy. We are trying to leverage the adaptive display from XD 5.6.

RE: ThinOS 8.0 + T10 + XenDesktop 5.6 = Audio stuttering when playing video.

I am in a very similiar scenarion (T10 with XenApp 6.5) and experienced the same issue with audio and video playback. The 8.0_030 firmware is unworkable in this scenario.

Hello BradBurnc,
Could you please validate your testing results with 8.0_033 posted above, and if still negative, please define your testing criteria and environment so that we can attempt to replicate your experience.

Thanks
John

RE: ThinOS 8.0 + T10 + XenDesktop 5.6 = Audio stuttering when playing video.

John,

I tried the 8.0_033 and the device repeatedly locked up before I was even able to try the video/audio testing. I have a picture I took to show what it looks like when the device locks up--basically a gray rectangle in the middle of the display. My setup is XenApp 6.5 running on Windows Server 2008 R2 on XenServer on Cisco UCS. I only run ICA in my environment and in this case I was about 300 meters from the datacenter (no latency or bandwidth issues) over a wired network. Let me know if you need any more information and how I can send you the picture of the locked screen if you need to see it.

Thanks,
Chris

RE: ThinOS 8.0 + T10 + XenDesktop 5.6 = Audio stuttering when playing video.

I did some additional troubleshooting yesterday and think I can trace the issue to an newly introduced incompatibility with the Lenovo USB Soundbar (part # 0A36190). When I unplugged the sound bar from the T10, I no longer experienced any freezing issues with the T10. This soundbar is quite popular within my company so if this incompatibility issue is real than it poses a problem for me.

RE: ThinOS 8.0 + T10 + XenDesktop 5.6 = Audio stuttering when playing video.

thanks for your mail, but there is no info on the pic
could you use the ini to generate core dump?
privilege=high enabletrace=yes upload=usb

if dev still cannot fix the issue by using core dump, i'm afraid we need the device. (please ask John about the process)
