I have connected my Onkyo 705 with Oppo 981 through HDMI and Coaxial. A Samsung 5 series 46" is connected to the Onkyo through HDMI.
I have a strange problem for which I need help. While I choose the HDMI connection between Onkyo and Oppo, the Onkyo display says "DVD No Signal" till such time the TV is switched on. The moment TV is switced on, both audio and video signal shows up on TV and well as indicated on the Onkyo Display.
This is OK for me, except while I want to listen just to 2.1 music without video. Ofcourse, the option is to use the coaxial connection, which I do for now. (Or turn on the TV, which is a waste of power). The real issue is that the coaxial connection will not work for SACDs and DVD-A and I dont want to spend on 6 RCA cables which is an alternate that I am aware for this format.
However, this problem goes away if I keep the "HDMI Monitor" setting to "no" in Onkyo 705. But, this means that no video signal can be output from Onkyo to TV and is a larger issue as I have my other components connected via the Onkyo to the TV. These are Tata Sky and another low end DVD player.
The onkyo mannual says something (which I don't fully understand) to the effect that this problem will happen and is natural.
Does that mean one cannot use HDMI between the Oppo and Onkyo for just audio.
Will I have to keep the TV on even if the format is just audio?
Do I have to necessarily go for a co-axial or analog connection (for SACD) for sound and avoid HDMI?
Does this sound like a problem and if yes, is the problem with Oppo or Onkyo?
Appreciate your thoughts
