I have read the same question posed.... I have the same issue.. I had hit * 4 times... multiple times over multiple days.... I have gone into settings. I know it happened one day when I hit a few buttons on the Roku remote.... I want it to SHUT UP. I saw where someone when to their Sony and found talk back... will there is not 'talk back' or anything similar on the LG settings.... and nothing on the Roku.... please can someone give me the way to fix this. I don't want to know the volume number as it goes up and down... and that the TV is turning off - or on... or anything else it has decided to tell me.
@SKVH, the Roku device has no idea what volume number your TV is set to, so it's the TV announcing the volume. Look in its accessibility settings. Samsung and LG TVs are known to use a long press of the mute button to access accessibility settings, so if your Roku remote has volume controls, that may have been what happened.
It COULD be this:
BUT -- I've never had a Roku connected to a non-Roku TV cause the TV volume setting to be announced audibly. The visual display of volume setting and any audible announcement likely are coming from your TV, not your Roku. You might want to check your LG TV settings.
IR remotes are very simple devices and they try to keep everything separated by giving each brand sperate codes, but sometimes if there is some interference (light), or multiple buttons get pressed, or the remote is aimed so products barely see the signal, or someone moves, and then something gets confused and product B interprets a button press on product A’s remote as some completely different command on product B.
I experience it around once a year. Then I grab product B’s remote and figure out how to undo whatever happened. It happens to my parents too and it confuses them that this can happen with product B’s remote safely hidden away. (Which I need to find to undo it.)
