Topic: Weird distortion when "on" before PC is "on"
I have experienced very weird distortions. They sound like a lot of wine glasses rattling in a cupboard to the rhythm of the music. They start out minimal, then they become more pronounced and louder until the normal audio has faded away and there's only distortion left. All of this happens within a few minutes. I use the ADI-2 DAC with USB as an external soundcard and it doesn't matter whether the audio comes from a game, or youtube, or foobar. After pausing the audio and restarting the audio the situation improves for a short time. Then the distortion starts again.
I have found a way to get rid of the problem. I think it happens when the ADI-2 DAC is switched on before the PC is switched on. When I make sure that the PC is running before turning on the ADI-2 DAC there aren't any problems. The problem also appears when the PC wakes up after hybernation / sleep and the ADI-2 DAC was turned on while the PC was hyberating (making the ADI-2 DAC think that the PC was turned off).
In either case the ADI-2 DAC shows that it is using the internal clock. I don't know what else to tell you that might be helpful.
