Thank you for replying. I did a lot of searching on the mailing list for
Digital Audio Capabilities without finding your issue.

I know back with Raspbian OS on the RPI4 I had to create a Mythtv audio
device in a file called: $HOME/.asoundrc. This must be what you did with
the right parameters.

I'll test and report back. In my case Kodi and VLC both worked with Dolby
Digital.  Sometimes I see "Multi Channel In" on the display instead of
Dolby.  I think this must be content related.
