NOTE:
Warning message is displayed when you open, edit, or remove applications when you refresh the applications.
4. Refresh scope covers the aspects such as, application removed, added, duplicated, disabled, enabled, icon/title change, and
on/off desktop.
Active sessions that are started are not affected by application refresh.
5. The disconnect session can be reconnected after application refresh, if Automatic reconnection at logon is enabled in
remote connection.
Refreshing the Citrix applications automatically by using INI parameter
To automatically refresh the Citrix application, set the following INI parameter:
SessionConfig=ICA RefreshTimeOut=dd:hh:mm
For example, 01:01:22, means the application will start refresh automatically, every 1 day: 1 hour: 22 minutes.
Limitations of Citrix icon refresh
Following are the limitations of Citrix icon refresh:
● Citrix icon refresh is supported in classic mode and storefront mode only.
● Virtual Desktop Infrastructure (VDI) mode is not supported.
Using multiple audio in Citrix session
ThinOS supports multiple audio device utilizations in the Citrix Virtual Apps and Desktops version 7.6 and later. You can connect
or disconnect the audio devices anytime during the session, but the behavior is similar to a local desktop. With multiple device
support, you can connect multiple audio devices and select a specific device for a specific application.
The Audio Plug N Play policy must be enabled on the Citrix Remote Desktop Session (RDS) desktop. The Audio Plug N Play
policy setting allows or prevents the use of multiple audio devices to record and play sound. This setting is enabled by default.
NOTE: On the Citrix Virtual Desktop Infrastructure (VDI) desktop, pre-configuration is not required.
Supported devices—USB headset, webcam (without USB redirection), and analog headset devices are supported.
The following are valid working conditions for multiple audio:
● Using Citrix HDX generic audio
1. Select the audio device as PC Mic and Speaker.
2. Configure the speaker or microphone.
3. For secondary ringer, select the audio devices excluding the devices that are already selected.
● Using Citrix RealTime Multimedia Engine (RTME)
1. Select the audio device as HID headset with PC Mic and Speaker.
2. Set PC Mic and Speaker to configure the speaker or microphone.
3. For secondary ringer, select the audio devices excluding the devices that are already selected.
The following scenarios must be considered during multiple audio settings:
● ThinOS default audio is set to the latest plug-in audio device.
● Session default audio is set to the ThinOS default audio. However, this option can be changed.
● Restart Skype for Business/Lync client after you plug in and remove the device.
● ICA RTP audio is supported with multiple audio connections.
