Thank you for that your response. With the information you have provided we would recommend still reaching out to the manufacture of the soundbar to ensure it is working as it should be but to also ensure that it is compatible with our device.
I’ve contacted B & O support, as you suggest. I hope you understand what I mean though about unnecessary pairing of devices connected via ARC and the inability to remove the soundbar from the 360’s pairing settings. Can you please pass this onto your development team (or whoever actually develops the Horizon platform - Liberty Global?). I can elaborate and work with a fellow developer if they are interested.
If you go into Audio & Video -> Pair remote with devices and accept the first audio setup key test as working (even though it doesn’t), then a new Volume keys control option is displayed under Pair remote with devices. From there I can change it to LG TV and the volume control then works correctly.
I have a Beosound Stage soundbar with my setup. It was installed about 6 months ago and works perfectly. I do not know what settings are used as it was all set up by B&O installers and plumbed in with the TV and V6 box - since upgraded to 360 - by them. I do remember there was an initial sound problem but that was solved by an overnight update to the B&O software requested by the installers. This was done remotely from Denmark. It would be a good idea to check that you are on the latest software version. My software version is 2.2.40830.
