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.
  • During a call, the audio device settings can be switched without plugging in or plugging out the device.
  • Multiple audio can be shared across sessions.
Limitations
  • Wyse 3010 thin client with ThinOS and Wyse 3020 thin client with ThinOS are not supported.
  • In Wyse 3030 LT thin client with ThinOS, set the DP audio as the default audio device to use DP audio in a session. Else, the DP audio will not available in the session.
  • Citrix multiple audio feature does not work with HDX generic audio. The resolution for the issue will be delivered in the next ThinOS release.
