I have recently got a Bose Soundbar 700 and it worked fine for few minutes with HDMI Arc and stopped working later. I have tried all the possible things mentioned in the other posts but no luck. This very annoying and I feel like I got a product not worth for its price. I need urgent help, I want to know if this can be fixed else I can return the product within 14 days. My TV model: Samsung UA50HU7000
Thanks for posting and welcome to the Bose Community.
I apologize about the frustration you're having with your new Soundbar 700, but I'd like to help.
We would suggest disabling AnyNet+ in your Samsung TV settings, and other helpful tips can be found in this video HERE.
Let us know if this helps.

I have tried the steps in the video and It has fixed the issue. But the soundbar stopped working on the second day. I have to repeat the whole process again in order to get it worked. This is quite annoying, I cannot do this every second day. Is there a permanent fix for this issue?

I am sorry to hear you continue to have difficulty, but would like to assist. If you cannot get the ARC connection to work we recommend using the included optical audio cable which will give you the same sound quality experience.
