I disagree I have a Dell T3400 with a Gigabyte 9800 1GB connected to a Samsung 40" TV via a DVI to HDMI cable and it does indeed pass audio. There is even a connector on the Graphics card to connect to the Sound cards digital audio out. This is on a 10 year old PC running Windows 10 for CD, DVD and Blu Ray playback but has the audio on HDMI to the TV for wife mode when I want to play a DVD but don't want to fool with the receiver. Why do we need so many remotes? Many Video cards do produce audio from the DVI but the cable needs to be fully wired.
