Re: Radeon HD 3000, No sound over DVI
I have never in my life seen audio coming out of a DVI connector my friend neither from VGA. Only from HDMI or normal analog audio connectors (the ones u use for headphones and such). That is why you dont detect it as audio hardware
HDMI audio should work though. I would suggest checking on the mythbuntu forums (unless that's here and I didnt know). I remember that to get audio working on my nVidia GT230 I had to do something about it, like use a custom thing (I did it for xbmc and it worked, now I can choose between 5.1 analog and the digital hdmi).
But, DVI... is video only, not audio. HDMI is video and audio.
