NAD M33 cutting first second of song while streaming

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. 

The M33 qualifies, it has HDMI, so possibly.

I did a factory reset, it seems to have worked.  If anyone one else experiences that first second dropped on streamed tunes, give it a shot, it worked for me.  (so far... lol)

That didn't work for long either.  So, the question still exists, does anyone have a solution that works for longer than a few hours?  NAD's solutions have not yet worked.

Great news and relief... on Thanksgiving night 2021 when I went into the BluOS app, it generated an automatic update to my M33.  Not an update to the app., but the system software in the unit.  That did the trick.  No more cut offs.  I've always loved the sound, but the cut off glitch was very annoying.  Not anymore... just the sound complete with the first note of a song.  Now I can stop cruising the ads.... fat chance... lol.
