I'm using a Sharc EZ Extender attached to a ADV7622. I feed in a 5.1 signal with a video (total 7 channels, from a Protools session) as input to the ADV board and noticed that I can either output just the video or just the audio as HDMI out from the ADV to a PC.
However, I'm able to receive both video and audio from HDMI out when I send a signal from a PS3. Is there a limitation on the HDMI output for a PC? How can I overcome this?
