I'm trying extract audio from an HDMI signal. Specifically, the monitor I'm using has no speakers and only has a DVI-D input, and I would like to play the audio track on a set of external speakers.
I purchased some cheap HDMI audio extractor (HDMI-in, HDMI & 3.5mm audio out), and it works with my regular TV that has HDMI inputs, but not with my monitor setup (video signal passes through, no analog audio output). Is this behavior I should expect?
That is, by using an HDMI to DVI-D adapter for the output, is the audio channel somehow no longer being requested/sent through the HDMI cable, so that the extractor can no longer intercept the audio signal?
Or is there some other cheap alternative hack I can try?
