I’m currently using the Sprout100 with a computer that doesn’t have an optical port nor headers on the motherboard to add one, so I’m using audio over HDMI and separating the audio signal to be used with optical. I have an extractor similar to https://www.amazon.com/gp/product/B074HHSJVN/ but made by Insignia (same ports). I’m able to hear the audio when plugging headphones directly into the extractor so I do not believe it is at fault, but I get no sound from the DAC when running a toslink from the extractor to the DAC. I have tried multiple optical cables in-case one was broken but none work. I’ve also tried running optical directly from a TV to the DAC and it still outputs no sound.
I do not have any other inputs plugged into the DAC and it is on Digital mode as expected. Is this an issue with the DAC and is there a way I can verify this?
EDIT: I tested with audio over USB and that works fine.
