In the Analog Out section, set it to
2 Speakers.
Headphone: This sets so that audio comes out from the headphone jack
2 Speakers: This sets so that audio comes out from the red and white RCA out
FP Headphone: This sets so that audio comes out from the front panel of your casing (the green colored, or w/e color the jack is on your PC case). Setting this option will
SHOW the amplification options (
HP Advanced Settings: Normal/High/Extra High Gain )
FP 2 Speakers: This sets so that audio comes out from the front panel of your casing (the green colored, or w/e color the jack is on your PC case) Setting this option will
HIDE the amplification options instead, showing only '
Speaker Test'.
To confirm that you successfully changed to the mode you want, in this case the '
2 Speakers' mode, make sure you can hear the '
click' sound from the card which is the sound of the electrical relays switching. It is the same sound you should be hearing upon booting up your computer. This is probably harder to hear if you have a silent/sound proofed computer case.
The next step would be configuring your stereo receiver's options, assuming your connection would be kind of like this: Xonar Essence STX > RCA Out > RCA in from the Stereo Receiver > Headphones/Speakers. This would probably look like Source: 'Line In' depending on your stereo receiver.
If you're still not getting any sound, check the power connector (molex) if it's properly connected to the STX card. Make sure when changing modes, you should be hearing the audible click from the card itself, OR, you can hear the sound from the STX's headphone out.
If all else fails, uinstall the driver, unseat and reseat the card, re-install the drivers, repeat the above.
Hope this helps.
