Using multiple audio in Citrix session
ThinOS Lite 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 specic device for a specic application.
As a prerequisite, 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, preconguration 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:
a Select the audio device as PC Mic and Speaker.
b Congure the speaker or microphone.
c For secondary ringer, select the audio devices excluding the HDX devices.
• Using Citrix RealTime Multimedia Engine (RTME):
a Select the audio device as HID headset with PC Mic and Speaker.
b Set PC Mic and Speaker to congure the speaker or microphone.
c For secondary ringer, select the audio devices excluding the RTME devices.
The following scenarios must be considered during multiple audio settings:
• ThinOS Lite default audio must be set to latest plug-in audio device.
• Session default audio must be set to the ThinOS Lite default audio. However, this option can be changed.
• Restart Skype for Business/Lync client after you plug and remove the device connection.
• ICA RTP audio is supported with multiple audio connections.
• During a call, the audio device settings can be switched without connecting the device.
• Multiple audio can be shared across sessions.
Limitations
• Wyse 3010 zero client with Citrix and Wyse 3020 zero client with Citrix are not supported.
• Citrix multiple audio feature does not work with HDX generic audio. The resolution for the issue will be delivered in the next ThinOS
release.
Using Citrix NetScaler with CensorNet MFA authentication
SMS PASSCODE is re-branded as CensorNet MFA. You can congure NetScaler Gateway to use a One Time Passcode/Password (OTP)
in the form of a personal identication number (PIN) or passcode. To obtain this one-time password, you must install CensorNet app on
your mobile. After you enter the passcode or PIN, the authentication server invalidates the one-time password. You cannot enter the same
PIN or password again. For more information about conguring one-time passcode, see the Citrix documentation.
Prerequisites
• NetScaler v12.0 and later is installed on your client.
• SMS PASSCODE v9.0 SP1 is installed and congured in your network. You can download the SMS PASSCODE v9.0 le from
download.smspasscode.com/public/6260/SmsPasscode-900sp1.
• Remote Authentication Dial-In User Service (RADIUS) authentication policy is congured and bind to the NetScaler gateway server.
• CensorNet app is installed and congured on your mobile device.
