Thanks @Hydrology that's a shame,.
I don't understand why more streamers don't have hdmi arc, the blue sound powernode has this feature, but not the blue sound node,
I had a realy cheap sound bar that had it so it can't be that hard / expencive to add to a streamer.
there must be a market for a streamer/DAC that you can use for both music and two Chanel TV
my old streammagic V1 will not last forever so hopefully Cambridge audio or bluesound include hdmi arc on a future product ( < $1600 )
thank again for the information
