Why does my Plasma TV have HDMI AUDIO IN jacks for my 2 HDMI inputs? Doesnt HDMI provide the Audio already?

Answer 1

They're probably there as backup audio inputs to handle the case where your source device has DVI output but no HDMI output and you are using a DVI-to-HDMI converter. DVI does not carry audio.

Answer 2

Those are used with a DVI video connector on older DVD and Cable boxes...

DVI only has video signals on it , so when you connect a DVI output, using a DVI to HDMI cable, you need to also connect the RCA Audio output to those connectors on the HDMI input....

Your manufacturer has some genuises on the Engineering staff , that's for sure....they know what they're doing....
