Hello guys , i have a very weird problem with my k7
when i go on a channel that has mpeg track .i can control the volume just fine .
when i go on a channel with ac3 track the volume is fixed ...............the volume bar appears and goes up and down but the volume does not change . even the mute doesnt work ........but the mute econ appears and desappears .....................i have tried all the setting but .it simply doesnt work.
any ideas ?
