5.Troubleshooting
I cannot install the audio card driver in my PC.
English
1.
(1). Ensure that you have switched the USB sound card to USB Audio 2.0 and
plugged it to the USB port.
(2). Make sure that the LEDs light up.
(3). Ensure that you have the latest driver version.
(4). Check that the Windwos hardware Device Manager has detected the device.
(5). Restart your computer.
(6). Try to plug the device into another USB port.
2. I cannot find the Xonar U7 MKII Audio Center.
(1). Make sure you have installed the driver.
(2). Find the Xonar U7 MKII Audio Center icon in the system tray on the right
bottom of the screen. Double click the icon to launch the Xonar U7 MKII
Audio Center utility.
(3). If you cannot find the icon in the system tray, go to the Windows Control
Panel and double click the Xonar U7 MKII Audio Center icon to make it
visible in the system tray again.
(4). After the driver installation is complete, it’s recommended that you reboot
your computer to complete the setup. If the icon still doesn’t appear, please
try installing the driver package again.
3. I can’t hear any sound from my analog speakers
(1). Ensure that you have connected speakers properly and have powered on
your speakers.
(2). Ensure that the device master volume or the software player has NOT been
muted in the Xonar U7 MKII Audio Center.
(3). Ensure that the output LED indicator matches the output source configured in
the device.

English
(4). If you are using Dolby Digital Live encoder through the S/PDIF output, the
analog output will be muted to get rid of the interference between your digital
speaker system and analog speakers or headphones. Please check if this is
the case.
(5). Please go to the sound and audio device of Windows® Control Panel to check
whether the playback default device is set to Xonar U7 MKII Audio Device,
instead of other onboard AC97 or HDA codec device. If it’s not, please set it
to Xonar U7 MKII Audio Device and restart your applications.
(6). Restart your computer.
4. I can’t hear any sound from the S/PDIF output
(1). Ensure that you have enabled S/PDIF output in the Audio Center GUI (Main
page).
(2). Ensure that you have connected the correct S/PDIF output jack in the card to
the decoder’s (AV receiver) S/PDIF input jack.
(3). You may need to select the correct input and mode of your decoder or AV
receiver. For Dolby Digital or DTS output, double check that the AV receiver
is in that decoding mode.
(4). If you are using 192KHz PCM output, make sure that your decoder can
support 192KHz decoding. Try changing it to 44.1K or 48KHz first.
