White Noise Through SPDIF When No Audio Playing
I have an Asus Xonar STX soundcard, outputting sound through an SPDIF connection to an external DAC. When I'm not playing back any audio, I get hissing, white noise. When I play back any sort of audio, everything is perfect.
From what I gather, the issue may be that the DAC isn't receiving any signal from the soundcard until something is played, in which case it works just fine. Is there any way to fix this issue?
