TX-55HX700B Soundbar & Internal Speakers Issue


Standard Member
Hi all - I have a TX-55HX700B (Android TV) with a soundbar hooked up over HDMI ARC so I can control the volume of the SB with the TV remote.

Nothing special, but I have an issue where when the TV Turns on or Off - there's about 5 seconds where the audio is coming from the TV speakers and can be REALLY LOUD. I have tried, turning off the soundbar and turning the internal speakers down to 0. This works for a while, but after some time the volume of internal speakers is reset. And we are blasted with loud volume when we turn on / off the TV.

I have read up that there is a hidden "Hotel Mode Menu" that allows you to disable the internal speakers. But nothing seems to work for my model TV (TX-55HX700B).

Does anyone have a solution to this?
