SONOS PLAYBAR SetAVTransportURI fail

[yamatakau08]

I used Sonos Ruby control program.
It works find and feel great.

This writing doesn’t matter your program’s issue.
Since you have expertise in control Sonos products, I need your help.

I’m trying to play DMS content on Sonos PLAYBAR on my Ruby Script.
When I execute SetAVTransportURI on PLAYBAR, PLAYBAR replys error code 714.
But other DMR can play the contents I specified, but PLAYBAR doesn’t.

I suspect the root cause in metadata.
How do I modifiy metadata to play DMS contents on PLAYBAR?
Do you have any advice?
Your help are very appreciated.

The following is the arguments data on SetAVTransportURI to PLAYBAR.
