TV: Vizio P65-F1 new in Dec 2018
Audio Setup: RCA Audio out (stereo) to good quality powered small box speakers
Audio Setting on Vizio: internal speakers set to OFF since using above for audio. BTW, good powered "monitor" box speakers BLOW AWAY sound bars.
Pairing Roku remote to Vizio was successful. TV Power On and Volume bar illuminates.
As of about 2 weeks ago, Roku remote volume control worked. Now it only works if I Turn On the internal TV speakers, which is intolerable since they interfere with my external box speaker setup.
Soliciting informed help on how to remedy this problem no doubt caused by a recent VIZIO firmware update intended to force TV owners to buy a Vizio soundbar.
