I can connect to the Citrix gateway via VPN from my Linux computer at home. This works without errors. But I can't get my Plantronics Savi 7xx headset connected to Jabber. If I work directly on the company thin client, I see a message in Jabber that there is no VDI client (here the headset is connected directly to the Cisco phone at the workplace).
If I am connected from home, I do not see this message. So I assume that the VDI client is then connected correctly. But I do not see my headset.
For testing I have installed a Windows 10 in a virtual machine on the same computer at home and from there I see the headphone in Jabber.
The question now is how can I find out why I don't see the headphone when connected from Linux? What can I do?
Our administrators can not help me so far
Annotation: The headset works on the Linux system without any problems. I can record sound with it and listen to it. So the hardware works so far.
On my local computer is installed: Cisco_JVDI_Client_Thinpro_and_Ubuntu-x86_64-12.8.0
I have completely reinstalled Ubuntu 20.04 LTS. According to the requirements, this version is supported . Then I installed the ICA Client (icaclient_126.96.36.199_amd64.deb) and tested the connection via the Citrix XenAppWeb. This worked. As expected, I then get a message in Jabber that there is no VDI.
Then I installed the JVDI client (cisco_jvdi_client-188.8.131.521886.x86_64.deb). Connected again and the message in Jabber does not appear anymore.
Ok, so far the status as before.
After looking at the source packages (.deb), I was able to understand at least somewhat how the software is supposed to work. I found out in the meantime that the vxc service is not started automatically. If I start it manually (systemctl start vxc.service) , I see messages in /var/log/cisco. Among others this error message: vxc: error while loading shared libraries: libpng12.so.0 I was able to fix this by manually installing the corresponding lib.
In the file /var/log/cisco/vxc_ui.log you can see that the Plantronics headset is also recognized correctly. However, there are several other strange error messages. Among others in the /var/log/cisco/vxc.log: "X Server is not alive, exiting." It seems that things are still going wrong here.
Now I have no more idea :- (
Here is the connection status of Jabber:
