I have the same issue as described by this chap -
But when I look at the setting mentioned (HDMI Input Audio Format) it’s greyed out? Should the TV be prepped by changing a setting before the Beam is plugged in or could there be another setting somewhere that needs tweaking before the above setting becomes available? If it provides a possible clue….when I select the speech enhancement option in the Sonos app, it doesn’t appear to make any difference, well, if it does then it is very, very subtle!
Thanks
