I don't tested it on a4k, but a1200+mediator it this card doesn't work now. I tried it with to different terratec 128i. The result: first it can be replay the test sound, but then never. The second one i tried to go further but no luck. You can hear the card's "bumming sound ", when you turn on your machine. And there is a flip-flop when os4 boots. (Same as when you want to hear the test sound in ahi prefs.)
However tunenet siply don't play the music, and cannot quit. Digibooster pro simply cannot play the music.
