Thanks I will give that a shot.
Update: I full rebooted the hub (batteries out and power pulled for 15 mins) and still no luck finding my R1. I have removed the device and even removed the DTH and SA completely. I have left the discovery window open for several minutes and nothing - even tried going the manual way Market Place > Speakers > Samsung Multiroom Audio > Connect Now. Tried restoring the speaker and re-adding to the network. Nothing has worked yet. Any other suggestions?
I was very much looking forward to this and the last issue I anticipated was getting it to paired w/ ST.
Update II: The R1 was added but never came up in the add window. I have followed @Gutheinz instructions and all appears to be working. Any notifications or sounds I have to select the R1 w/ lan audio dth to have it work but does pause/resume music on the customer dth. Thank you for your help!
