Irregular sound levels from Sonos Beam when streaming different apps on Sony Bravia H80 4k television

I bought a Sonos Beam sound bar two days ago.  I love its robust sweet sound and voice clarity.  I was disappointed when I brought it home and connected to my television.  I am using an HDMI arc cable for connection.  I chose not to load any apps on the sound bar because all I watch/hear is on my internet driven television.  As you know, the sound bar’s’s volume is driven by the television remote..  Here is the issue:  When I open Netflix, Prime Video and Disney Plus apps, and watch a movie, I need to turn the volume on the tv almost all the way to the max to get almost adequate sound coming out of sound bar.  When I open my You Tube, Apple TV, ABC News Live, CBS All Access and Spotify, I get a range of adequate volume depending on the app.  Spotify plays perfect at a volume level of 20 out of 100;  You Tube needs to be upped to about 40/100; Apple TV and the news apps need to be in the 50 out of 100 volume range.  I also have a Sony Blu Ray player that is connected to the television via a HDMI cable on the non arc connector.  Same problem playing movies of concerts from DVD player - turn volume all the way up to get almost adequate sound.  It concerns me that I have to turn the television volume all the way up to get almost adequate sound for most of my movie channels.  I fear it will eventually damage my television.  I feel that something is not right.  I have had two other soundbars with this television earlier this year, and neither of them had this problem, and they were connected the same way.  I followed the “robust information” in the set up book that Sonos provided.  I finally found the right Sonos app (out of 8 Sonos apps) to DL to control EQ, etc.  I am older and not a very tech savvy person.  I feel that I had set up correctly, but something is funky.  Anyone else had to deal with issue?  How did you correct it?
