Took delivery of my first smart TV Saturday & still getting into the controls. First impression, the PDF manual is rubbish, doesn't find half the queries I entered. Last night we watched the BBC episode of Poldark, & was surprised when it started as there was a female voice giving a commentary on the action. I had a quick look through the sound options, but as we didn't want to miss the action, gave up trying to remove the background voice. When the show finished, I had another go & think I have removed it, but as there hasn't been a similar transmission since can't be sure. I have it now set at internal speaker only, I think it was set on Internal speaker + Audio Out (optical). Can anyone confirm this?
