15.6. USB Headsets

15.6.1. Tested USB Headsets
15.6.2. Tested Applications
15.6.3. Additional Notes

There are a number of USB headsets that have been tested to work on Sun Ray 2 Series and Sun Ray 3 Series Clients.

Once the latest firmware is installed on a Sun Ray Client, no other special installation is required for USB headsets to work. When using USB headsets in a Windows session (uttsc), the USB redirection feature is not required. However, for Windows XP and Windows Server 2003 R2, you do need to install the Audio Input component. See Section 17.4, “Audio Input” for details.

For some USB headsets, you must use the utsettings command (Sun Ray Settings GUI) to change the mute and volume settings, even though there may be inline buttons or controls on the headset. For most of the USB headsets, the Sun Ray Settings GUI can be used to adjust the audio settings.

See Section 13.2.3, “How to Change Sun Ray Client Audio and Display Settings (Sun Ray Settings GUI)” for details.

15.6.1. Tested USB Headsets

For the list of tested USB Headsets, see the Sun Ray Client and Oracle Virtual Desktop Client Peripherals document.


When using a USB headset in a Window session (uttsc command or fullscreen Windows kiosk mode), the Sun Ray Settings GUI is not available. In this situation, use the audio settings from the Windows desktop.


When using the Sun Ray Settings GUI, setting Mic Gain to 0 or de-selecting the Microphone button will not mute the microphone. To ensure the microphone is muted, disable the audio input in your application.

When using uttsc, sound input redirection from the Sun Ray Client to the Windows server is disabled by default, which means the microphone is muted for all applications running on the Windows server. You need to use the uttsc -r soundin: option to enable it.

15.6.2. Tested Applications

The following applications have been tested to work with USB headsets when using a remote desktop session through the Windows connector:

  • Skype 5.2 - Windows 7, Windows XP

  • Ekiga - Windows 7

  • Adobe ConnectNow - Windows 7

15.6.3. Additional Notes

  • When both an analog headset and a USB headset are connected to a Sun Ray Client, the USB headset is used.

  • Only one USB headset per Sun Ray Client is supported. If more than one USB headset is connected to a Sun Ray Client at the same time, the last USB headset connected will work. Disconnecting any one of the USB headsets will cause the audio to switch back to the Sun Ray Client's built-in audio device.

  • Connecting two different USB audio devices to a Sun Ray Client is not supported. For example, connecting one USB speaker and one USB microphone to a Sun Ray Client is not supported.

  • A USB headset and a Sun Ray Client's built-in speaker cannot provide audio output at the same time.

  • When using the uttsc command, you can use the -r sound: and -r soundin: options of the uttsc command to change the sample rate quality of the audio input or output for a Windows session.
