Welcome to DC-Talk!
Hmm I'm a little confused. I don't know of any hdmi cables for the Dreamcast unless you purchased a vga to hdmi converter box. Also, VGA doesn't carry sound through it. Do you have link to this hdmi/vga thing you purchased so we can check it out? It should have 1/8" audio out jack on it or maybe RCA (red/white) audio outputs. In that case you could run that to you TV or external speakers for audio.
