7. Troubleshooting and FAQs 7.1 Troubleshooting Q1. The audio card driver could not be installed on my PC. 1. Check that the audio card is properly inserted into the PCIe slot on your motherboard. 2. Run Windows hardware Device Manager and check if a multimedia audio device is listed. If no device is detected, scan manually for hardware changes. 3. Reboot Windows. 4. If Windows still fails to detect the audio card, insert the audio card in a different PCIe slot. Q2.
Q4. I cannot hear any sound from the S/PDIF output. 1. Check that you have enabled S/PDIF output in the Audio Center GUI. 2. Check that you connected the correct S/PDIF output port on the card to the decoder’s (AV receiver) S/PDIF input port. 3. You may need to select the correct input and mode of your decoder or AV receiver. 4. If you are using 96KHz or 192KHz PCM output, make sure your decoder can support 96KHz or 192KHz decoding. Change the PCM output to 44.
Vocal effects can still be applied by using commercial or free audio editing software to convert the sound files to 48KHz. Please note that the frequency meter on the Xonar D-KARAX Audio Center will not take effect when the playback source is at a 96KHz or 192KHz sample rate to prevent any processing distortion. 36 ASUS Xonar D-KARAX PCIe 7.
