Bluesound Node volume pot setting for an integrated amp

Sorry, I have the Node 2i which does not have HDMI input as does your new version Node.

So the HDMI out from my Roku is input into the HDMI in of the TV, and the TV audio analog out into my preamp.  Unfortunately, does not get the benefit of my DAC. 

what @jetter said

fuzztone;

   I know but my blind wife needs as few buttons and settings to do as 

possible . She has the voice activated roku .

well...a little of everything sort of

I disconnected the ARC from the Node but left it plugged into the tv. Now

the roku volume indicates that it is disabled.

The optical goes from the tv to the int. amp. which is using the DAC in the amp.

And RCA from the Node to the amp. Which uses the DAC from the Node.

Now playing the two volume pot thing when streaming with the Node only 

It works and sounds good but the aggravation is something else !

Now...how do I stop the Node from streaming an app when not in use ?

Thanks
