I've posted a similar question before but apparently someone made it no longer exist.
Basically, how do you know that an SPDIF signal coming from a sound card and going to an external DAC is actually working and is an SPDIF signal. The reason I ask is because I am still able to control the sound characteristics from my soundcard, which leads me to believe that it is still doing all of the processing and just using the external receiver/DAC for power.
Can anyone clarify this for me, or am I misinformed about how SPDIF should work?
