of course at the end (with some rare exception...) there's a dac that converts signal from digital domain to electric signal (line), and that needs to be amplified to move speakers (power). where you plug a mini jack, an rca, an xlr connector, well, inside there the dac you're using. of course we should avoid sound board dac, and even when you use HDMI you do it in digital domain until is decoded, converted and sent to internal dac of the black box called home theater.

i think you and i know the issues

can we have your full debug log (wiki) now?
