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 specic device for a specic 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

a Select the audio device as HID headset with PC Mic and Speaker.
