I've been using hdmi for video only for 2 years and optical for audio. I got a new lg lhb535 receiver with 2 hdmi and and plan to just use hdmi for video and audio. Only problem is I get video only. No audio at all. Other hdmi sources play audio and video just fine. I see lots of reported issues on the web of the 722 and hdmi issues. Any suggestions? I've tried new cables. Rebooting everything in different orders. Resetting the 722 to default and setting back up. No luck.
