I have an issue with my Opéra de Paris.
It is working perfectly with other Bluetooth devices but when I connect it to my Samsung QE75Q the sound is flickering and almost inaudible.
Does anyone else experience this issue?
Thanks a lot for your help!

So just fixed it - You need to buy a wifi router that supports the 5 GHz frequency. Apparently bluetooth cannot work properly near 2.4 GHz wi-fi. I bought a new router - connected it - everything works great.

(The same solution would be to connect the speakers to the Internet via wlan / or connect to the TV via an optical cable)
