In an attempt to simplify my home theater set-up for my wife, I ran into an interesting problem with volume control. I have a Vizio E421VO tv with an Xbox 360 and Playstation 3 connected to the tv via HDMI. The tv has an analog audio out via 3.5" jack, which I have running to an old RCA stereo, which is connecting using red and white RCA connections. I attempted to change the tv's analog audio control setting to variable, so the volume of programming would be controled by the tv, not the stereo. I discovered, after talking with Vizio support, that when the analog audio of the tv is set to variable, the tv tries to control the physical volume of the stereo though the 3.5" connection when pulling audio from an HDMI connection. In short, I would get no volume from HDMI connections because the stereo can't process the extra information. I would like to continue using the stereo for amplification, which leads me to my question: Is there a digital to analog audio convertor in which the tv can control the volume? So, audio would come out of the tv via optical, run to the convertor, and then from the convertor to the stereo via RCA cables and the tv would control the audio volume output of the convertor. I know it is a strange situation, but I would really appreciate any help or ideas. If anything needs clarified, just let me know.
