So about a month ago I switched up my audio out cable. I was using a standard 3.5mm audio cable for simplicity, but decided to take full advantage of my headset and switched to using the fiber optic for high definition surround sound. When I'm on the high definition channel (Realtek Digital Output), I get awful crackling sound during audio and sometimes during load times, whether sound is involved or not.
Yes, I have googled this concern and got tons of results; from the updating/reinstalling the driver, checking "Disable all sound effects" in the Enhancements tab, and watching my latency for possible disruption.
None of the aforementioned remedies worked. I have concluded that it very well could be my fiber optic cable itself, being that when I move it the crackling gets worse and sometimes better.
Before you comment "You solved your own problem, why are you posting here," there's more to it.
-Sometimes the crackling is worse than other times.
Example, I can't listen to any music right now because the crackling is unbearable.
About 20 minutes ago I was listening to music 100%, as if nothing was of error.
Sometimes the sound gets better, after having it on for an hour or so.
;;The only thing that changed between now and 20 minutes ago, is that my computer went to sleep.
So if my cable was indeed at fault - why does it sometimes get really bad, sometimes it's fine, and sometimes it gets better?
Is it that the drivers have to reload, since the computer went into sleep mode? - if so, why does the cable effect it?
I suppose I'm looking for the science behind fiber optic cables (can the signal "buffer" per se, or strengthen as it travels?).
