HDMI Audio?

Open tmzt opened this issue 3 years ago • 9 comments

Is there any way to support HDMI Audio output with this, maybe with mostly static graphics (now playing or album art)?

It should be possible but I haven't implemented it.

I would love to have audio. Maybe I can help implement it?

@Wren6991 I'd like to look into the audio aspect, at the very least for my own projects. Do you have a link to a reference where you got the info for the DVI/HDMI communications protocol?

I second the proposal to the HDMI audio, also where could we find information about technical implementation.
