I have an old MacBook Pro, with DVI-out video, analog audio (earphone and speaker ports), and of course USB. I'm using it to manage my iTunes library, but the only way to play iTunes content on my home entertainment system is via Wi-Fi to an Apple TV box.
My question: Is there a viable way to connect the Mac to an open HDMI port on my home system? I know that DVI-to-HDMI is video only, so I'd have to find out how to add the audio -- which is the whole point of the exercise! (Is there any such thing as an analog-to-HDMI or USB-to-HDMI audio adapter?)
