I can hear sound, but the sound settings show no soundcard. There is no indicator until I uncheck and check the "show sound volume in menu bar" but then it show just muted, sliders have no effect. Media key are also not working. It "thinks" there is no soundcard even when it is working.
Sidequestion: whats are this audio controllers on new graphics cards? Are there just to pass the sound from the real soundcard to the HDMI cable or is it actually a real soundcard in there?
