Hi SajH,
Thanks for your post and welcome to the forums. It's great having you on board with us in the Community.
I'm afraid there isn't much advice we can offer you on this since we're not able to support third party equipment.
The community may have some advice to offer though as many of the users have good technical knowledge of the sound bars and the best settings to connect them on.
Failing that, you can sign up to our Gadget Rescue service who also may be able to help.
Let us know if you have any further issues.
Thanks,
