My soundbar is a 3.1.2 setup initially. This means it's a 3 speakers (Left, Centre, Right) all towards front of sound bar. The 1 is a sub woofer and the 2 represents top speakers towards either end of soundbar for Dolby Atmos.
Later I got rear wireless speakers making the complete setup as 5.1.2..
Now, we have been watching episodes of Sheldon series on Amazon Prime and I'm able to hear sound from rear speakers. But, I don't know if its 5.1 Dolby sound or nor. Any inputs.. Thanks in advance.
