Noticed something: set up: Samsung HW-K650 + 2 R5 speakers In multichannel mode over wifi - if i turn up the volume with the remote control of the samsung smart tv the volume goes up on all speakers - while if i turn up the volume with the soundbar controller, the R5 speakers go immediately half the volume of the soundbar speaker. Is this normal? i have to go back to the tv controller turn the volume down to zero and than bring it back up and it is all level on all three speakers.  Another thing, on the multiroom app i am in surround mode (5ch), i have set up the balance to max for the rear speakers and mid for soundbar.  All good so far.   What do you guys think?  ...
