Had this for over 18 months now and although it's a great picture, using an external soundbar is essential. Unfortunately, since the May update, the sound bar connected via HDMI ARC no longer works. If I use the optical connection, it works but with no surround sound and is prone to the known fault of randomly switching the soundbar on when the TV is off. Also, I have tried the trick of disconnecting everything, reconnecting just the ARC connection and it worked until the following day then stopped again (I've tried this twice). I have now spent hours trying to sort this. Do you know if I can return the TV to John Lewis under their 5 year guarantee?</P> Thu, 22 Jul 2021 08:50:32 GMT Workerant2 2021-07-22T08:50:32Z https://community.sony.nl/t5/android-tv/more-external-sound-bar-problems-after-update/m-p/3815910#M55703 <P>KD-55AG8BU 4K OLED TV.

Also, is the soundbar Sony?</P> Thu, 05 Aug 2021 13:56:05 GMT https://community.sony.nl/t5/android-tv/more-external-sound-bar-problems-after-update/m-p/3818406#M55883 HannahEd01 2021-08-05T13:56:05Z
