as the title indicates I have recently purchased and acquired. The ultimate Immersive Arc Ultra Set, which includes the arc ultra, a pair of ERA 300s and one Gen 4 sub… because I wanted a more thorough home theater experience. I went ahead and purchased an additional GEN4 sub, as well as a pair of ERA 100s. 
 

-firstly I was very disappointed in being unable to add the ERA 100 into the one home theater setup… I was only able to add the GEN 4 sub… I had to add the ERA 100s, As a separate group, which was then merged.

 

Now they all work together when I watch TV. And although every couple of times I turn something on, sound will only come out of one of them, But that’s a different concern… My concern here is how can I Control the volume for my television with my Roku remote, such that raising or lowering the volume, does it to both the theater set up as well as the merged ERA 100s? — right now the only way to raise or lower the volume of both is in the Sonos app, Which is extremely frustrating.

Please help

A TV or Roku remote can only control the volume on the speakers in the home theater setup. It cannot control the volume on any grouped speakers.

Just curious… where did you place the pair of Era 100 speakers? Do you notice any delay on those speakers when playing TV audio?


First of all you can only connect one set of surrounds to a Sonos soundbar. Your remote will work with a soundbar to control the volume of components directly under its control (sub and surrounds).  You can’t force the system to do something it wasn’t designed to do.


The only way I am aware of, is to use Sonos voice control, or Alexa voice control, to adjust the ‘group volume’ - I’m a little surprised that you do not notice the slight delay/echo effect caused by the extra Era-100s when playing TV audio to the group🤔. That said, I’m assuming you have not adjusted the ‘TV Dialog Sync’ setting on the Arc Ultra?
 

The likely reason the TV sound sometimes drops out on the Era 100s is possibly you have ‘ungroup on Autoplay’ set in the Arc Ultra room settings… at least, that’s my first thought.
