Don't know if this applies but I have this problem (first second music dropout) when my player is connected to a preamp/receiver with HDMI. There is a known interface problem (User manual for Sony 5400 Player has a notification) with HDMI. Something with the "handshake" protocol. Problem first noticed about ten years ago (Sony 5400) and still have problem with my Sony 4K disk player.
NAD M33 cutting first second of song while streaming
While streaming, I haven't tried another source, my NAD M33 sometimes cuts off the first second of a song. I've seen this problem posted in several forums, but haven't seen a solution short of bringing it into a factory service center. It seems like a firmware issue, but if so, would have been solved by now, I would have thought. Anyone have a solution?
