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 Audio Device, instead of other onboard AC97 or HDA codec device. If it's not, please set it to Xonar U7 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.
