hmm. my tv does have audio RCA jacks, but i'm not sure if they're available for the HDMI "channel" you select on the TV. perhaps I should test. If that's the case then I may aswell just send the RCA out from the amiga straight to the TV RCA in, if it runs in parallel to the HDMI. If not, i will need to find some way of sending the audio in digital form as it would for standard HDMI with audio.
would be cool to have a more "modern" way of having one lead be plug and play into modern TV's for both video and audio though
only difference is the connections have swapped, the monitor (RGB) port being used for legacy TV and DVI for PC monitors tehehe.
