I am attempting to setup a Sonos Arc + Sub with a Samsung MU8000TV from 2017 (UN65MU8000FXZA). I am running into issues at every turn, but I will start with the beginning:
First off, I have an existing Sonos S1 setup in place all with old Amps (this will come into play with one of my issues). I did setup a new Sonos S2 implementation, and was able to add the Sonos Arc and Sub into a new Room. The Sonos Arc is connected to the HDMI4 input on the TV, which is labeled as HDMI ARC. In the settings for the TV, I have configured HDMI Input Audio Format as Bitstream. As soon as the Arc was added, the Sonos app attempts to perform the TV setup. When I get to the “Test connection” part, it fails every time, with the error “ARC Mode not connected”. That’s my first issue. Any reason why this is not working?
For now, I just exit out of the TV Setup in the Sonos app (but I would like to get that working!). The next issue is actually getting sound out of the Sonos Arc when playing something from another device connected to my Samsung TV, an Apple TV 4K. No matter what I did, the Sonos Arc would just not output any sound. The only way I can get any sound to output (and that includes menu confirmation sounds from the TV when accessing the Samsung TV’s menu) is to select TV Autoplay in the Sonos app within the Room settings. I don’t understand why I have to do this, and I have no idea if this is a good thing or a bad thing, but I find it odd that I had to select that option to get any sound out of my Samsung TV. Is it supposed to work when you do not have TV Autoplay selected?
I figured I would just keep going with my setup, so I moved on to configuring the Arc to work with my Logitech Harmony remote that utilizes the Harmony Hub. In the Harmony app, I went to add a new device, and searched for Sonos Arc. At that point, the Harmony app does a scan on my network for Sonos devices. Unfortunately, it only finds all of my old Sonos Amps running on the existing Sonos S1 configuration. Rescanning just finds the same items. So when I am presented the list of Sonos devices (all Amps and no Arc), and I de-select all of the Amps, all I’m left with is a Skip button that simply exits adding a new device without actually adding anything. I only want to use my Harmony Remote for controlling the volume on the Sonos Arc, so I need to get this working.
I was really looking forward to getting everything setup and working properly, so any responses would be appreciated.
