I want to be able to "ask" the dac or a patch if it is producing audio.
I was looking at doing something like this;
This produces 1 when audio is being produces and 0 when it's not, however the problem is I don't know how to bang this setup to acquire the playing state.
I'd like to ask it, "are you playing audio?" and then get a single response, yes / no.
Does anyone have a suggestion as to how I might proceed with this?
