I want to make the AV1 Audio (Right, Left) input the default audio input while using the HDMI 1 input the default Video input.
Said, another way, can I disable the HDMI 1 audio input on the RCA 42LA55RS, but retain the video? Anyone know how?
I have a Comcast set top box that only has DVI output. So I use a DVI to HDMI cable (HDMI input on the RCA TV). I use the RCA jack (Red, White) for audio out from the set top box to the TV RCA input jacks.
However, I can't get any sound.
I *can* "block" inputs (e.g. HDMI 1) to the RCA TV, but if I do that it also blocks the video.
Thanks for any help, the picture looks great, just need sound!
