Lync loses speaker in Citrix Session RRS feed

  • Question

  • I have the following setup:

    2008 R2 with all patches and SP
    Citrix Xenapp 6.5 with all patches
    Lync 2010 with all patches

    When I login to my Citrix session I can make a call but after 5-30 minutes I lose the speaker. I cant hear what the other person is saying. The microphone is still working though so the other person can hear me.

    All other sounds in citrix session also stops when Lync loses the speaker. But when I hang up the Lync Call the sound in the session returns. But Lync never gets back the speaker sound.

    The only way to get the speaker back in Lync is to logout from the session and login again.

    I guess it is a Citrix related problem because i have not seen the issue on the locally installed clients.

    I also have a Xenapp with an older version of Xenapp and there we have no problem with the lync client.

    Anyone running Lync in Xenapp 6.5 and have you had any problems?

  • Seems like it was the version 13 of the reciever that was the problem. Installed:  CU13.1.300

    That I got from Citrix and now I have a Lync call running for 40 minutes with no problem and excellent sound quality.

  • I know that Microsoft does not support Lync in Citrix but with Xenapp 6.5 Citrix is supporting it.
    And as I said it almost works flawlessly in Xenapp 6.0. And with Xenapp 6.5 you have even better support.

    I have now tested with MSN and the same problem occurs when making a call in MSN. So it seems to be Citrix related somehow.

  • If you use any Remote Desktop or Server Virtualization then the only supported modality is Instant Messaging & Presence.

    It is not supported to use media over Citrix session.
    You must either use an IP Phone to connect the audio or use a local full softclient on the pc.

  • As John says, unfortunately media isn't supported in citrix. That being said, citrix do have some suggested configurations that they suggest will work.

    Can you try a call on something like Skype or MSN to see if its a Lync or Citrix issue

    thanks

  • So then you must contact Citrix if they do support it.

  • Hi,Harmankardon,

    Since it's Citrix related you'd better contact Citrix support center to have an support engineer look at this problem,or you can post the question to Citrix support forum for more professional help.

    Besides,you can try to check the hotfixes for Xenapp 6.5 and fully patch the Citrix application to see if it works.

    Hope this useful!

    B/R

  • I've also heared from a number of customers expiriencing same problem. The best workaround at the moment is to "pause" the call for few moments then audio comes back.

  • The Citrix article ID: CTX133607 includes a link to this version of the Receiver, but is not available for download unless you have a current Citrix tech support contract.  Would you be able to email me the CU13.1.300 download?
