RU9, Courage, with the H1055 hooked on my onkyo 608 via HDMI, coaxial and composite the receiver should have detected and played the audio because the onkyo automatically detects the available audio signal, either HDMI, coaxial or composite. Initially I was worrying that the culprit was the receiver because i have not actually tested on using the receiver's composite and coaxial audio inputs. But when i used my egreat m34a having the same audio setup, the audio played on the 3 audio inputs. I toggled on HDMI, coaxial and the composite (RCA left and right) and the audio sounded clear.
