Since i bought this, i noticed sound is very less when i watch the channel via using this box. I connected this box with my TV connected with HDMI Cable but it does not produce 5.1 Channel sound. I even tried to connect with Optical Cable (Box has this provision) with Boss Sound Receiver but still sound is very less . I have to increase the full volume of my remote , even sound is only like coming from mono speakers.
As well, when Buzz TV application starts and logo appears, no sound come at all. My other old Buzz TV Box produce sound when logo appears.
