After update firmware 3.08.14 . We’re can not off voice of singer because we use file music vob. for karaoke ?
We push on icon audio on remote for chose chanel 1 or chanel 2 . ex : chanel 1 = music and voice play .
chanel 2 = music only , and now we’re chose for both = music and voice play .We’re not off voice ?
How can delete new firmware and install back old fimware ?
