Hi -- I'm running a DAC+ Pro on a Pi3 with Runeaudio and am having a strange problem. Occasionally I will perceive a sudden change in the soundstage imaging, with instruments, vocals, etc. hopping quickly to different parts of the image. It sounds almost as if something is introducing phase shifts in to the output, shifting the phasing of the drivers. Once or twice I've heard (imagined?) a soft "pop" accompanying this shift. This has happened on a variety of recordings, and does not repeat in the same position of the song, so I'm certain it's either a hardware or a software issue. Can someone comment on what might be causing this, and what a possible solution might be? Thanks!
