I've had this amp for several years but have yet to hook it up to to limitations with renting. Now that I am in a location where I could set it up I wired everythign together last night. I've got my cable box, PS3 and Apple TV wired via HDMI in to my Mitsubishi WD57734 tv, and then a digital audio out from there to my receiver. The audio plays fine through the receiver, but it only shows and plays stereo sound, and not 5.1. I've triple checked all of my input sources to make sure they are Dolby Digital 5.1 and I've even tried running an optical audio directly from both the PS3 and the Apple TV to the receiver to see if that would change anything. Unfortunately, no matter what I do, all I get is the stereo sound. If I use the remote to switch to surround, the display still only shows two speakers with information, and not all six. What am I doing wrong?
If you connect your sources directly to the HK 247 with HDMI it'll decode the Dolby Digital 5.1 audio you're looking for.
Unfortunately your HK only has 2 HDMI inputs so I'd recommend keeping the cable box connected to the TV with HDMI and then using an optical cable from the cable box to the HK for audio. You'll still get Dolby digital that way vs using the optical out on the TV.
don't have a Apple TV so not sure what 5.1 sources pass thru it.
But optical from your cable box should work for 5.1.
