Sonos Arc with Samsung tv HDMI not working properly

I have seen problems similar to mine discussed here but I am unable to see if they were resolved. I have a Samsung NEO QN90A tv that is a little over two years old. I recently purchased a Sonos ARC and connected it to the tv with an HDMI 2.1 cable. If I enable eARC the sound is garbled. If I turn eARC off the sound is OK with the exception of sporadic short drop outs. These seem random and occur on a scale of tens of minutes. Annoying! I now have the tv connected using the optical adapter that came with the soundbar and it works OK with the exception of not supporting ATMOS. Is there anything I can do to get HDMI to work?

If you are only using the TV’s native apps, keep the HDMI-eARC Mode setting on the TV set to OFF.

And try this:

Disconnect everything from the TV and unplug the Arc and TV from power for a couple of minutes. Plug everything back in but keep everything disconnected. Make sure Anynet+ is enabled in the TV settings. Run TV Setup in the Sonos app and follow the app instructions. When the app instructs you, connect the Arc to the TV’s HDMI ARC/eARC port using the Sonos-supplied HDMI cable.

Make sure the Digital Output Audio Format setting is set to Pass-Through, not Auto.

    There is nothing to pass through. I am trying to get the tv sound. As a result pass through is grayed out.

      I did just exactly as instructed in this response and thus far have had no problems with the sporadic drop outs. I’m not sure why the exact sequence of installation should be important but it seems it is.

      Thank you.
