How to tell whether a graphics card supports audio over HDMI?

How to tell whether a graphics card supports audio over HDMI? I want to connect up my desktop PC to a TV via HDMI for watching video on, in addition to a normal (DVI) desktop monitor. Ideally, I would like the audio and video to go through the HDMI cable to the TV.
