Installing the EVGA NU Audio card should be a smooth process without any hiccups. But if any problems arise while using your NU Audio card, we recommend trying to troubleshoot the issue by performing the following steps:

1) Shut the system off and ensure that the NU Audio card is correctly installed in the motherboard. Sometimes simply removing the card and reseating it in the PCIe slot can resolve any issues.

2) Ensure that a SATA power connector from your power supply is firmly connected to the SATA power plug at the rear of the NU Audio card. **Please note that a molex to SATA adapter will not be sufficient to power the NU Audio card**

3) Make sure that the front panel connector from your case is connected to front panel audio header along the side of the NU Audio card.

4) Once the NU Audio card is confirmed to be correctly installed into the motherboard, you will want to ensure that the latest drivers are installed in your operating system. You can find drivers for all EVGA products at the link here: https://www.evga.com/support/download/. For further information on specifically installing the NU Audio drivers, we would recommend reading the information at the FAQ linked here: http://www.evga.com/support/faq/?f=59758.

5) Double-check that any audio devices (such as headphones, speakers, etc.) are plugged directly into the NU Audio card. Any other output jacks you may have on the system should remain unpopulated for proper playback through the NU Audio card.

6) Check that all audio cables are properly connected to the NU Audio card as well as the speakers/headphones themselves. If you are using any adapters (such as a 3.5mm to 6.3mm adapter) test without any adapters or a different cable if possible.

7) Close any other audio controlling programs that may be installed on the system. Programs for onboard motherboard audio are often installed and it is recommended to disable those programs to prevent any conflicts with the NU Audio card. You may also want to consider disabling any other system audio devices through your Windows device manager.

8) If you are experiencing issues and are running Windows 7 on your system, please see our FAQ linked here: http://www.evga.com/support/faq/?f=59761.
