I use RPi as a media player with raspbian and omxplayer.
My hardware system: RPi ->[HDMI]-> Sony Bravia TV ->[Audio Cable]-> Microlab Stereo.
I have a problem with 6 channel audio: voice is very silent. It seems that center channels used for voice in 5.1 audio, and my stereo system just has no these channels.
Is there a way for playing such video with normalized sound on RPi?
