I have a Samsung TV and soundbar and I'm now using only one remote.
I'm sorry if I'm just repeating what has already been covered. I just wasn't understanding a few things. By page 4 of this thread, it finally clicked into place in my feeble brain thanks to post #113 by denpom and the link provided. Just passing it forward.
The problem is that, to me, the hookup is counter intuitive and Samsung support does not have a handle on their products.
-I have a Tivo Premier 4, Samsung UN55F6400AF TV and the HW-F450 sound bar.
-I have an HDMI cable out of the Tivo to the TV's HDMI in 1 (STB)
-I then have the TV's HDMI in 2 (ARC) to the sound bar's HDMI out.
-I'm using no other cables.
-I went into TV settings menu and turned on Anynet+ and set auto turn off to "yes". Some have had to set auto off to "no". Don't know why.
-I believe that at this point I already had the sound bar's Anynet+ turned on. The next step may not have otherwise worked.
-I hit the "more" button on the tv remote and hit tools, clicked on Anynet+ and hit refresh. It searched for and configured the sound bar, even though there is still no device in the "select device" window. At one point, I had assumed that meant the sound bar wasn't seen by the TV. I was wrong.
-I hit speaker select and checked receiver.
When I turn on the setup, the D. IN pops up on the sound bar but within a few seconds it switches to TV ARC and sound comes through.
Then I needed to program the dang Tivo remote. The Tivo gives three codes for A/V volume and mute on Samsung receivers. None of these work. I used the first code in the Samsung TV code list, code 0305. But program the remote using the receiver control method. Yes, a Samsung TV code for a Samsung receiver. About as backwards as everything else. Hold the TIVO and mute buttons until the light goes off and then comes back on to stay, then hit the code, 0305 You get three blinks, then Voi'la! A one remote solution.
There is a strange anomaly when powering up everything The Tivo switches to live mode on a random channel, different than the one I was previously on, even if the channel or recording playback was paused when I had just turned off the TV/sound bar. Oh well.
To me, this HDMI routing shouldn't work. Every time my mother-in-law has a power outage or hooks up a new TV, I have to explain the concept of inputs and outputs and signal paths to get her back on track. But that gets thrown out here. I'm thinking "why the heck would information travel OUTWARDS through a TV's HDMI INPUT and INWARDS through the sound bar's HDMI OUTPUT?" But apparently it does.
And judging from one of the manuals, it appeared to me that an ARC was a path from the Tivo, through the sound bar, into the TV. I was wrong. Sound and video would pass through but, like some of you, I could use one remote to turn the sound bar on/off OR adjust volume, depending on how I tweaked the setup. But not on/off AND volume.
Hope this ridiculously drawn out walkthrough helps some poor soul.
